New Central-Vac System with Air Purge Technology

Minimize the Health and Explosive
risks associated with dust.
Introducing Walinga's newest Central-Vac System with Air Purge, featuring a much smaller footprint, more consistent suction, a ‘Dumpster Full’ Auto Shutdown and cyclically self-cleaning filters. The Walinga Central-Vac with Air Purge is designed in accordance with NFPA guidelines.

4 Self-Cleaning Filters

Powerful Air Purge technology cleans four internal air filters automatically. No more time consuming manual filter cleanings required. Save time. Save money.

Smaller Footprint

Walinga’s Air Purge Central Vacuum System takes up minimal space while maintaining the same robust power and Walinga reliability customers expect. 

The new Air Purge Primary Cyclone combines three traditional components, the primary cyclone and bin, a secondary cyclone and bin plus filter canister into one integrated Air Purge Primary Cyclone unit.

One component replacing three means simpler installation on a smaller footprint with far less maintenance.

Clean-Up and Transfer Almost Anything

Upset the Explosion Equation

Removing Dust and Dispersion from the Dust Explosion Equation* greatly reduces risk.
