Air-Tight Blast Gates
Ruwac's air-tight blast gates operate manually or pneumatically, and utilize a two part, self-sealing gasket assembly to completely isolate outside air, guaranteeing no air leakage across the valve or into the atmosphere. They are designed to withstand 16 HG” of negative pressure.
These blast gates are manufactured in zinc plate or stainless steel in 2”, 3”, 4”, 6” and 8” diameter and can be installed on any dust collection or vacuum system. Pneumatic valves are available with coil voltages ranging from 24V AC/DC to 120V AC or 220 V AC and operate off air pressures as low as 30 Psi, with optimal performance requiring 70 Psi. Supplied as standard with straight ends, Ruwac’s air-tight blast gates can also be made with flanged or rolled ends when required.
