Heavy Duty Cast Iron Airlocks

HDT model Drop Thru rotary airlock feeders are designed for rugged applications that require an outboard bearing style unit where contamination and/or an abrasive product cannot be handled with an inboard bearing style RAL.



The HDT is engineered for use in high pressure pneumatic conveying systems with 400˚F application temperatures where more of an effective seal is required due to high or excessive wear that is experienced with a simple dust collector RAL.
