FACTORY-BUILT · CAPTURE AT THE BENCH

Plug-and-Play Downdraft Grinding Tables —
No Ducting, No Central System Required

For single grinding and polishing stations, a central dust network is overkill. XinXie EP builds self-contained downdraft tables — 5,400 m³/h of capture drawn through the work surface and backdraft panel, cleaned by four anti-static PTFE cartridges and returned to the room. Roll it into position, plug it in, and start grinding: units shown here are in service at client sites in Sichuan and Chongqing.

Product Overview

One Bench = Capture, Filtration, Fan and Dust Drawer

Grinding dust is dangerous — metal particles inhaled through the respiratory tract are linked to occupational lung disease, and fine dust escaping into the workshop coats every surface. The downdraft table solves it at the source:

▪
Capture without interfering with work — air is drawn down through the perforated work surface and in through the backdraft panel, so fine suspended dust never reaches the operator's breathing zone while tools, hands and line of sight stay free
▪
Four-stage media, built in — large particles drop into the collection drawer, fine dust is caught on the outside of four anti-static PTFE cartridges; cleaned air is discharged evenly through a grille at low noise
▪
Clean air returns to the room — no ductwork, no make-up air penalty, no heated air exhausted outdoors in winter; energy that a central system would throw away stays in the building
▪
Explosion-protection as standard — explosion-proof motor and control box, anti-static filter media, and an explosion vent panel on the body, built for combustible metal dust duty

Design Details

Engineered for Fine Metal Dust and Long Shifts

Every detail of the bench pushes toward the same goals: steady suction, safe handling of combustible metal dust, and maintenance a workshop operator can do without calling a technician.

1 · Downflow + Backdraft Capture

Air enters through the perforated tabletop and the slotted backdraft panel, sweeping dust away from the operator's face and down into the machine — capture that follows the workpiece instead of chasing it with a movable arm.

2 · Anti-Static PTFE Cartridges

Four Ø325 × 600 mm cartridges give 44 m² of anti-static PTFE media. At 0.3 µm filtration and > 99% efficiency they handle fine, damp and tacky metal dust that quickly blinds ordinary media.

3 · Pulse or Manual Cleaning

A pulse-jet controller (0.4–0.6 MPa, adjustable width/interval/rows) strips the dust cake without stopping the fan; a manual reverse-blow version is available. Suction stays constant between cleaning cycles.

4 · Three Lines of Fire Defense

Flame-retardant mesh on the inlet chamber, anti-static media, and an explosion vent panel on the body — protection designed for the spark and combustible-dust reality of grinding and polishing.

5 · Quiet, Even Discharge

Cleaned air leaves through a full-width grille that spreads the outflow evenly, keeping noise below 85 dB(A) — and because the air is clean, it recirculates inside the workshop instead of being exhausted and re-heated.

6 · Serviceable in Minutes

Sealed dust drawers empty with a triangle key; cartridges swap from the front; braked casters let one person reposition the bench. No ducting, no permits, no rigging — place, plug, grind.
