HD Aerolock with Air Purge Seals and optional Filter-Regulator kit
The T3 seal is our best seller, providing a Teflon® shaft insert anchored to the rotor shaft with three set screws. Two resilient double-point contact seals ride on the Teflon®, resulting in a long-lasting seal which is easy to maintain. When maintenance is required, simply loosen the set screws, remove and replace the T3 assembly, and retighten the set screws. The packing gland and lip seals are of standard industrial design.
Air purge seals are available on all models of Aerolock rotary valves. Equipped with an optional solenoid operated valve, filter and regulator, the seals are purged with plant air ported through the Aerolock rotary valve end plates. The purge air, being at a higher pressure than the air inside the Aerolock, flows inward through the seals, keeping the conveyed materials away from the bearings.
