Suction Blowing Systems

Polyvac (North America Only)

The Polyvac is an integrated solution that is uniquely designed for high capacity vacuum conveying.

The Polyvac unit is a combined blower, rotary valve and cyclone package which is designed for conveying granular materials. The top part, containing the blower, can be opened for cleaning and easy changing of cyclone filter basket.

The Polyvac is suitable for conveying plastic pellets, granules, or reprocessed material. When handling materials containing high quantities of dust, it is recommended that the outlet of the Polyvac be connected to a dust collection system.


Designed for high capacity suction conveying

Many conveying jobs in the plastic processing industry can be solved efficiently by using pneumatic conveying systems. In combination with ’s OK160 pipe system, complete systems for pure vacuum or vacuum-pressure conveying can be tailor-made to meet most conveying demands from process to process, or to and from a storage facility. A Polyvac solution ensures a more uniform material feeding rate.

Principle of Operation

The blower creates a strong vacuum necessary to pick up the material from point A and discharge it through the cyclone and a rotary valve to point B, either directly or through a pressure line.

No material passes through the fast-moving blower rotor, thus no additional dust is created in the material and also no excessive wear and tear on the blower housing and rotor.


A typical application for the Polyvac is conveying of pellets or regrind material. The Polyvac is very suitable for bulk conveying of pellets and regrind material from a gaylord or granulator to a molding machine or extruder.

The Polyvac is unique for the continuous evacuation of reprocessed material from shredders and granulators. It creates a strong vacuum and thereby ensures sufficient airflow through the granulator for cooling.

When used in combination with the KIA Aspirator solutions, the Polyvac feeds plastic regrind material into the Aspirator, where the material is cleaned and ready for re-use.
