C516 Fireproof Level A Dust Collection System Brings Non-Combustible Foam Dust Control to Mattress Plants

Qingdao, China — Xinmeiteng has added the C516 fireproof Level A dust collection system to its foam machinery range, a unit built for the dust that foam cutting, shredding and trimming produce every shift. The system pairs a non-combustible Level A cabinet with a cyclone separator and two 1500 mesh stainless steel filter elements, and is offered with a 1.5 kW or 2.2 kW motor on 220 V or 380 V supply.

Foam processors tend to treat dust as a housekeeping problem. In practice it is the most combustible material in the building. Fine PU and sponge dust has a large surface area relative to its mass, stays suspended in the air, and ignites at low energy. A dust cloud around a cutting head or a shredder outlet is a fire risk before it is a cleanliness issue.

That changes what a collector has to be. A unit built from plastic housings and combustible filter media adds fuel to the exact place where dust is concentrated. A collector built from non-combustible materials removes itself from the fire triangle instead of feeding it.

The C516 is built to a Level A non-combustible specification. The cabinet around the dust path and the filter chamber is metal, and the filter elements are stainless steel rather than treated paper or synthetic media. The machine weighs 200 kg and measures 1200 x 650 x 1750 mm, small enough to sit beside a cutting bay rather than in a separate plant room.

Air enters from the hood, passes through a cyclone separator that drops coarse foam dust out of the stream, then moves through two stainless steel elements rated at 1500 mesh. The first element carries the bulk of the fine dust load, the second polishes the air before discharge.

• Cyclone pre-separation keeps coarse dust off the filter, so suction holds longer between cleans.
• 2 x 1500 mesh stainless elements capture the fine airborne fraction that reaches operators.
• Washable media is cleaned and refitted, not replaced every cycle.
• Metal filter chamber keeps collected dust inside a non-combustible housing.

• Foam cutting rooms, with the hood at the blade;
• Shredding and granulating lines, at the shredder outlet;
• Rebond foam mixing and scrap handling areas;
• Mattress trimming and edging stations;
• CNC foam routing, with extraction at the cutting head;
• General workshop clean-up with a hose kit.

The 1.5 kW unit suits a single hood mounted close to the collector, typical for a small shop or one cutting machine. The 2.2 kW unit is intended for longer duct runs or two to three hoods open at the same time. Both versions use the same cyclone and the same two 1500 mesh elements, so filtration does not change with motor size. A 220 V version installs in a workshop without three-phase supply, while 380 V suits a production line.

The dust bin is emptied on a fixed schedule, the elements are washed at an interval set by the dust load, and the door seal and duct joints are checked weekly. Grounding the duct and the collector is part of the installation, and the filter chamber is only opened with the power isolated. A filter that is kept clean holds suction, and suction is what keeps dust entering the hood instead of settling on workshop surfaces.

The C516 is CE certified for export and available now, with delivery at 45 working days after downpayment. Both motor sizes and both voltage versions can be specified at the time of order. Duct connection sizes, filter specification and a commissioning checklist are supplied with each unit, with remote support during installation.
