Blower Air Lock
The blower air lock is a rotary valve that feeds product into a pressurised pneumatic line while sealing against air loss.

- HKBHK
The blower air lock takes product from above in the pockets of its rotor and releases it into the pressure line. The close clearance between rotor and housing prevents the conveying air from escaping upwards.
The rotor vanes are sized for the pressure difference and the tip seals are replaceable. A correctly selected air lock is a direct determinant of blower efficiency and conveying stability.
Capacity, motor rating, shaft diameter and dimensions are given in the model table. The side cover comes off so the complete rotor can be withdrawn.
Key features
- Rotor sized for the pressure difference
- Replaceable tip seals
- Complete rotor withdrawal through the side cover
- Low-speed operation with a geared drive
- Sealing that protects blower efficiency
Applications
- Pressure pneumatic conveying lines
- Feed points of blower pumps
- Flour and bran transfer systems
How it works
Working principle
Conveying moves grain and milled products between every stage of the plant with minimal energy and no product damage.
- 1Product enters the boot of the elevator from a conveyor or hopper.
- 2Buckets on an endless belt lift it up the loaded leg and over the head pulley.
- 3Centrifugal force throws the product into the discharge spout, from where screw or chain conveyors and pneumatic lines carry it on.
