Long-life filter cartridge technology
- Filter material: The mainstream materials are PTFE-coated polyester / nanofiber (BiCo two-component polyester), featuring a smooth surface, low adhesion, and washability for reuse.
- Structure: Large pleat spacing and large filtration area (20–30㎡/filter cartridge), resulting in high dust holding capacity.
- Lifespan: 12–24 months under normal operating conditions, 2–5 times longer than ordinary filter cartridges, significantly reducing replacement frequency and costs.
- Efficiency: MERV 14–16 / F9–H13, with an efficiency of ≥99.9% for 0.3μm particles.
Self-cleaning system
- Control methods: Differential pressure automatic control / Timed control / Manual control.
- Dust removal methods: Pulse jet cleaning (most commonly used), rotary reverse blowing, ultrasonic cleaning, etc.
- Benefits: Reduced manual maintenance, reduced downtime, stable airflow, extended filter element lifespan.
Other standard features
- Mobility: Bottom universal wheels for flexible adaptation to multiple workstations.
- Safety Design: Flame-retardant mesh, explosion-proof motor, anti-static filter cartridge, and overheat protection.
- Intelligent Control: Linked control of welding equipment start/stop, filter blockage alarm, and automatic airflow adjustment.
- Low Noise: Noise reduction design, typically ≤72dB (A).
