Industrial Metal Grinding Downdraft Table For Precision Component Dust Extraction

The Industrial Metal Grinding Downdraft Table is engineered to eliminate airborne dust, metal shavings, and fumes right at the point of generation—solving a critical pain point for metalworking shops. Its perforated work surface (1.2mm thick wear-resistant steel with 3mm diameter holes) creates uniform negative pressure, pulling contaminants downward through a two-stage filtration system: a pre-filter that captures 80% of particles ≥5μm (e.g., coarse steel swarf) and a HEPA H13 filter that traps 99.95% of particles ≥0.3μm (e.g., fine aluminum dust). This design prevents dust from spreading to workstations, protecting operators from respiratory risks and keeping equipment free of debris buildup that can cause malfunctions.

Designed to withstand the rigors of heavy-duty metalworking, the table features a 10-gauge cold-rolled steel frame with a corrosion-resistant epoxy-polyester powder coat—ideal for environments exposed to cutting fluids and metalworking oils. The work surface supports loads up to 500kg, easily handling heavy workpieces like steel gear blanks or cast iron housings. For flexibility, it comes with 4-inch polyurethane casters (2 with locking brakes), allowing smooth movement between CNC grinding machines, manual workstations, or assembly areas—no fixed installation required.

Whether you’re grinding high-tolerance automotive parts, deburring aerospace components, or polishing medical device hardware, this downdraft table adapts to your needs:

• Precision Grinding: Its vibration-damped worktop (reinforced with a 5mm steel underframe) minimizes surface wobble, ensuring consistent grinding depth for parts like hydraulic valve cores or aluminum piston rods (critical for meeting ±0.005mm tolerance requirements).
• Adjustable Airflow: A variable-speed fan (300–800 m³/h) lets you match airflow to task intensity—high speed for aggressive deburring of cast iron, low speed for delicate polishing of brass connectors.
• Clean Production Compliance: Meets ISO 14644-1 Class 8 cleanroom standards, making it suitable for manufacturing environments where even microscopic dust could compromise component quality (e.g., sensor housings or electronic connectors).

Routine upkeep is simplified with tool-free filter access—replace pre-filters or HEPA filters in 10 minutes or less. A built-in differential pressure gauge alerts operators when filters need servicing, reducing unplanned downtime. The table’s 0.75kW EC motor adjusts power usage based on airflow demand, cutting energy consumption by 30% compared to fixed-speed models—ideal for 2-shift or 3-shift operations looking to lower utility costs. An optional activated carbon filter module is also available to adsorb VOCs from grinding lubricants, addressing odor issues and meeting EPA emissions standards.

Fully compliant with OSHA 1910.94 (U.S. ventilation standards for metalworking) and EU EN 13205 (industrial air cleaning equipment), this downdraft table helps your shop avoid regulatory fines while protecting employee health.
