 C516 1.5kW/2.2kW Fireproof Level A Dust Collection System 1500 Mesh Filter for Foam Dust Removal

The C516 fireproof dust collection system removes the fine dust produced when blades are ground on foam cutting machines. Its stainless steel filter cartridges are rated Level A non-combustible, its cyclone separator keeps filters from clogging as fast, and its built-in silencer keeps the workshop quieter. With 1.5kW or 2.2kW motor options and 220V/380V supply, it is designed as supporting equipment for peeling machines, horizontal cutting machines and vertical cutting machines.

Foam cutting machines do not only cut foam; their blades need grinding, and grinding produces dust. A band knife, a horizontal cutting blade or a vertical cutting blade is sharpened on the machine, and the sharpening action throws off a mixture of fine metal particles and foam powder. Left in the air, that dust settles on the machine, on the floor and on the freshly cut foam, and it becomes a fire and health issue in a workshop that is already full of combustible material.

The C516 is built for that specific job. It draws the dust away at the grinding point, separates the coarse fraction in a cyclone, and traps the fine fraction in stainless steel filter cartridges. The cleaned air returns to the workshop, which matters in a production hall where sending heated or cooled air outside is expensive.

It is not a general-purpose industrial vacuum. It is a dedicated dust extraction unit for blade grinding on foam equipment, sized to be moved between machines and connected where the work is happening.

Flexible polyurethane foam dust is a genuine fire hazard. Fine foam particles have a very large surface area relative to their mass, they stay airborne, and they can ignite from a spark, a hot metal particle from grinding, or a static discharge. In a workshop full of foam blocks and offcuts, a dust collector that itself can burn is not a safety device; it is an additional risk.

The C516 addresses this with a Level A non-combustible rating. The stainless steel filter cartridges are the key part of that design: stainless steel does not fuel a fire the way a paper or fabric filter does, and it withstands the heat of sparks that reach the filter housing.

Three practical rules support the rating:

• Empty the collection point regularly. A full bin is a fuel load. Dust should not be left to accumulate over a weekend.
• Keep sparks out. Grinding sparks should be separated before they reach the filter; the cyclone does part of that work by dropping heavier particles out of the air stream.
• Ground the unit and the ducting. Static build-up in a dry dust stream is a real ignition source, and grounding is part of a safe installation.

The most common complaint about dust collectors in foam workshops is not filtration quality; it is filter cleaning. When all the dust reaches the filter, the filter blinds over quickly, airflow drops, and someone has to stop production and clean or replace it. In a busy shop that happens far too often.

The C516 uses one cyclone separator ahead of the filter stage. The cyclone spins the incoming air, and the heavier particles are thrown to the wall and drop into the collection container instead of loading the filter. Only the finer fraction reaches the stainless steel cartridges.

The result is a longer interval between cleaning, less labour spent on maintenance, and more stable airflow during the shift. For a factory that runs blade grinding several times a day, the labour saving alone often justifies the cyclone design.

The C516 carries two stainless steel filter cartridges rated at 1500 mesh. Mesh rating describes how fine the screen is; a 1500 mesh element captures very fine particles, which is what foam grinding dust mostly is.

Stainless steel has three practical advantages over disposable media in this application:

• Reusable: the cartridges can be cleaned and put back into service instead of being thrown away, which reduces consumable cost.
• Fire resistant: metal does not burn, and it tolerates sparks better than fabric media.
• Stable performance: a metal element does not degrade with moisture the way some media do, so filtration stays consistent in a humid workshop.

Two cartridges are fitted, which gives the unit enough filter area to keep airflow up as dust loads on the surface. Cleaning should be done with the unit switched off, using a soft brush or compressed air from the clean side, and the cartridges should be inspected for damage at the same time.

Dust collectors are often placed close to the machine they serve, which means close to the operator. A high-pitched whine from a vacuum unit running all shift is tiring, and tired operators make mistakes around moving blades.

The C516 includes a built-in silencer to reduce working noise. The aim is not silence; it is a noise level that allows normal conversation and instruction at the machine, so that the dust collector can stay switched on during production instead of being turned off to get some quiet.

That last point matters more than it sounds. A dust collector that is switched off for comfort is not protecting anyone. Reducing noise removes the incentive to switch it off.

• Cyclone separator. One cyclone stage removes the heavier dust before the air reaches the filters. It is the component responsible for the reduced cleaning frequency.
• Filter section. Two stainless steel cartridges at 1500 mesh handle the fine fraction. The filter housing is arranged so that the cartridges can be removed for cleaning without dismantling the unit.
• Motor and fan. The unit is available with a 1.5kW or 2.2kW motor, supplied for 220V or 380V. The motor drives the fan that creates the airflow through the cyclone and filters.
• Silencer, housing and collection container. The silencer is built into the air path. The housing is compact at 1200×650×1750mm and the complete unit weighs 200kg, so it can be positioned beside a machine and moved when the grinding station changes.

• Level A fireproof performance: non-combustible structure, fire retardant for foam workshop dust collection safety.
• Stainless steel filter cartridges: two 1500 mesh cartridges for stable fine dust filtration.
• Cyclone separator design: reduces filter clogging, cuts filter cleaning frequency and saves labour.
• Built-in silencer: lowers working noise and improves the workshop operating environment.
• Two power options: 1.5kW or 2.2kW motor, 220V or 380V supply.
• Global support: remote technical assistance, spare parts supply and installation guidance.

Motor power and voltage are selected at order. Confirm the supply available at your workshop before the order is fixed.

The C516 is supporting equipment, and its value depends on which machines it serves. In a typical foam line it is used at the grinding stations of:

• Peeling machine: the blade that peels foam into sheets is sharpened on the machine, producing a steady stream of fine dust.
• Horizontal cutting machine: long blades used for splitting blocks generate dust along the blade path during grinding.
• Vertical cutting machine: contour and vertical blades produce dust at the sharpening point as well as foam dust from cutting.
• Shredding and recycling stations: grinding and shredding equipment produces foam dust that should be captured at source.

Because the unit is compact and weighs 200kg, it can be placed next to the machine being serviced and connected with a short duct run. Short ducts keep airflow high and reduce the chance of dust settling in the pipe.

• Foam cutting workshop: dust removal during blade grinding of peeling, horizontal and vertical cutting machines.
• Sponge processing factory: dust collection at foam cutting and shredding work stations.
• Industrial workshop: dust purification for foam recycling and foam machining production lines.
• Blade maintenance areas: a dedicated extraction point where knives are ground and dressed.

A dust collector is only as good as its connection to the dust source. Three layout decisions decide whether the C516 performs as intended.

Distance. Keep the duct run as short and straight as possible. Every bend adds resistance, and a long run of flexible hose collapses under suction and traps dust.

Capture point. The hood or nozzle should sit close to the grinding point, ideally enclosing the dust rather than chasing it. A capture point half a metre away will collect some dust, but a large share will escape into the workshop.

Air return. The cleaned air leaves the unit and must be able to circulate. Do not box the unit into a corner with no clearance around the outlet; allow space for the air to move and for maintenance access to the filters.

If several machines are served by one unit, plan the ducting as a system with blast gates rather than running open branches, so that airflow stays high at whichever station is in use.

The C516 is offered with a 1.5kW or 2.2kW motor and can be supplied for 220V or 380V. The choice depends on the installation, not on preference.

• 1.5kW: a good match for a single grinding station with a short duct run, and for workshops where the available supply is limited.
• 2.2kW: more airflow reserve, which helps when the duct run is longer, when the capture hood cannot be placed close to the source, or when the unit serves more than one station.
• Voltage: select according to the supply actually available. A 380V unit cannot be run from a 220V outlet, and vice versa.

Oversizing has a cost in noise and power consumption, and undersizing has a cost in escaped dust. Give us the number of grinding stations and the duct length, and we will recommend the motor that fits.

• Floor: a level floor that can carry 200kg, with enough clearance around the unit for filter access.
• Ducting: connect the capture hood to the inlet with the shortest practical run; seal joints so that the unit does not draw dust-laden air from the workshop instead of the grinding point.
• Power: connect to the supply matching the selected motor and voltage, with correct protection and grounding.
• Test: run the unit and check suction at the capture point, listen for abnormal noise, and confirm that the airflow at the outlet is free.
• Training: show the operator how to check the collection container, how to clean the cartridges and when to stop the machine.

• Switch on before grinding. Start extraction before the blade touches the grinding wheel, so that the first burst of dust is captured.
• Keep the capture point close. Reposition the hood when the grinding position changes.
• Ground the unit. Static in a dry dust stream can ignite fine foam dust. Grounding the unit and the ducting is part of a safe installation.
• Do not open the unit while running. Switch off and isolate before opening the filter housing or emptying the container.
• Wear PPE. A dust mask and eye protection are still required at the grinding station, because extraction reduces dust but does not eliminate it.

• Daily: check the collection container and empty it before it fills. A full container reduces suction immediately.
• Weekly: clean the stainless steel cartridges and inspect them for damage or clogging; check the duct joints for leaks.
• Monthly: inspect the fan and motor for abnormal noise, check the silencer for blockage, and confirm grounding continuity.
• Spare parts: keep a spare set of cartridges and duct seals in stock so that cleaning and replacement do not stop production.

Because the cartridges are stainless steel, they are cleaned rather than replaced in normal service. Replacement is needed only when the mesh is damaged or permanently blinded.

Each unit is assembled and run before shipment: the fan and motor, the cyclone seal, the filter housing and the electrical connections are checked. The machine is CE certified.

The C516 weighs 200kg and measures 1200×650×1750mm, so it ships as a compact unit with the cartridges protected against transit damage. Delivery time is 45 working days after downpayment, with the final schedule confirmed when the order is placed.

1. Which machines will it serve? One grinding station or several; peeling, horizontal or vertical cutting machines.
2. How long is the duct run? Longer runs need the 2.2kW option to hold airflow.
3. What supply is available? 220V or 380V, matched to the selected motor.
4. How much dust is generated? Heavy grinding schedules justify the larger motor and more frequent container checks.

Send these details and we will confirm the motor and voltage option, the ducting plan and the delivery schedule.
