Northtech NT-RAL5 1/2HP Rotary Air Lock

Rotary Air Locks, often called RAL’s, are machines that are used to prevent air loss from a positive or negative pressure system, while separating dust or solid materials from one air flow to the other. The Northtech RAL5 Rotary Air Locks are a fabricated steel design with a multi-fin internal impeller that is powered by a strong 80:1 1/2HP drive. Optional connection fitting can be custom built for almost any application.
