Aspirator Cleaner - PAS Series


Aspirator cleaners (often referred to as “TARARA”) are a very widely used system for removing lighter parts and dust from granular material before ensilage and/or drying. They are characterised by their intrinsic simplicity, which has promoted their widespread diffusion. Metalmont PA Series cleaners are suitable for cleaning cereals, seeds and their derivatives.

In designing these products, Metalmont has scrupulously applied the latest and most stringent standards with regard to operator safety, reliability in the most arduous working conditions and construction quality, with the aim of reducing energy consumption and maintenance costs.

Metalmont PA Series cleaners are also available on request with ATEX 22 certification. The standard operating temperature range is 0 to 40 °C.
Information on our past installations and customer portfolio is available on request.


The range of Metalmont PAS Series cleaners comprises a single model. The fundamental indicative properties are:
Model Air Flow Rate Material Load Capacity Power Discharge Diameter
  m3/h t/h kW mm
PA 100/120 7500 100 4 / 7.5 320


Metalmont PAS Series cleaners do not have specifically dedicated accessories, but use other components produced by Metalmont (valves, fittings, pipes, rotary cleaner, cyclone...) hat facilitate their effective installation in the plant.

The only recommended device is the star valve at the material discharge outlet, available in the Metalmont catalogue, for use in combination with sepcific fittings where applicable. This valve uses a 0.75 kW gearmotor with IP 55 protection rating.

Metal joinery components: in addition to specific accessories for the correct installation of its machines, Metalmont is also a long-standing supplier of more general but equally useful plant access and structural solutions such as staircases, rest platforms, inspection platforms, walkways, frameworks and bracketing of all kinds, from simple brackets to backstays for supporting long sections of piping, shelves and stands.
