Heaslip Engineering Ltd. has considerable experience in the design of dust and fume extraction systems.

We are particularly experienced in the design of dust extraction systems for very abrasive materials. These systems are designed to be inherently balanced so that no flow control devices are required in the ducting.

A specially developed computer program enables duct sizes to be adjusted to obtain this equilibrium.
We are also experienced in the design of cyclones, pneumatically pulsed baghouses and dry scrubbing systems for noxious fumes.
