Amtech ATV series dust collectors are a single housing construction completely seam welded unit. This heavy duty construction gives both Torit and Farr dust collectors a run for the money and is evenly matched in all aspects of quality construction and feature design. The Amtech ATV series utilizes a patented down flow technology to prevent dust re-entrainment during cleaning cycles. The self-cleaning filter design uses a venturie pulse cleaning method to induce a higher volume of air for a more effective cleaning system. Construction: 11 gauge Carbon steel powder coated inside & outside CFM Capacity: 500 – 50,000 Compressed air Consumption: 2.5 CF/pulse Filter Configuration: Vertical filters with front access door for entry.
