Airlanco custom airlocks can be used with pneumatic systems, gravity feeds and volumetric discharge devices. Fabricated airlocks handle dust collection, plastics, feeds and corrosive chemicals where pressure differentials are 20 in. of water column or less. Machined airlocks are designed for higher pressures, as well as difficult and abrasive materials. Both airlock types are available with carbon and stainless steel rotor and housing options.
