Rotary Lobe Blowers
Proven low-pressure air movers for aeration, conveying and backwash, across every major make.
What they are
The classic tri-lobe and twin-lobe families that most plants were built around. Parts are plentiful, behaviour is predictable, and a well-kept lobe machine runs for decades.
What we do
- Routine servicing, oil and seal programmes.
- Full overhauls with rotor and clearance work.
- New and refurbished supply, bare shaft or packaged.
- Fast exchange units to keep a duty covered.
Getting the choice right
Twin or tri-lobe, belt or direct drive, bare shaft or packaged: the permutations matter less than matching the machine to the system and keeping the drive simple. On a steady duty, a fixed-speed machine with the right pulley ratio is hard to beat for cost and reliability.
Weigh parts availability too. The common families can be kept running for decades; a rare import can leave you waiting on one overseas warehouse.
What goes wrong
- Belt squeal or short belt life: alignment or tension, occasionally a tightening machine telling an early story.
- Gradual flow loss: lobe and casing wear, measurable in a health check long before the process feels it.
- Oil weeping at the ends: seals due, best done properly with the bearings inspected while it's open.
- Vibration rising: check the mounts and coupling before condemning the machine.
Typical duties
aeration lanes, sludge work, conveying, general low-pressure air.
