Product Description

This model features a compact size and easy mobility, making it well-suited for work in narrow spaces. The maintenance-free motor provides strong and lasting suction. It is suitable for metalworking, pharmaceutical and chemical industries, daily cleaning, and matching polishing and grinding work — vacuuming, water pickup, and iron filings collection can be completed in one pass.

Schneider Control System

The control switch adopts the Schneider control system, featuring overload, overheat, and phase-loss protection, with imported switch circuits for safe and reliable use.

Star-Shaped Coated Filter

Equipped with a large-area star-shaped coated filter, it filters 0.3μm fine dust with an efficiency of up to 99%.

Manual Dust-Shaking Device

The manual dust-shaking device shakes the dust off the filter from the outside, effectively cleaning the filter and preventing clogging.

Upper-and-Lower Tank Separation

The upper-and-lower tank separation structure is a standard configuration of this machine. When you need to empty the dust, simply lift the handle lever, and the collection tank will lower itself to the ground naturally. Pull it by its built-in casters to dump the dust, then press the lever back down to finish.

Pressure Monitoring System

The pressure monitoring system uses a vacuum pressure gauge to monitor the internal filter condition in real time, providing clogging alerts and preventing filter blockage from causing motor overload.
