Wet/Dry Spray

Spray booth

The new spray booth Extra is the latest development from Blowtherm aimed at the most demanding spray booth operator. It has been developed to provide exceptional results along with higher productivity. Equipped with the optional Blowpower system, the Model Extra provides exceptional performance in terms of energy saving, increased productivity, and environmental impact.

Cyclones and Multi Cyclones

Ashwa CycloneAshwa cyclone
Ashwa Cyclone

A high speed rotating (air flow is established within a cylindrical or conical container called a cyclone. Air flows in a spiral pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream and strike the outside wall, falling then to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone the rotational radius of the stream is reduced, separating smaller and smaller particles.

Wet Scrubbers

Ashwa Wet ScrubberWet Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. Wet scrubbers operate by introducing the dirty gas stream with a scrubbing liquid – typically water. Particulate or gases are collected in the scrubbing liquid. Wet scrubbers are generally the most appropriate air pollution control device for collecting both particulate and gas in a single system.

Pollution Systems offers a variety of Wet Scrubber systems specifically designed for your process application. Many important operating variables are considered when evaluating the size and type of scrubber for any specific application. We will work with you and use our experience and knowledge to provide the proper solution for your process.

Centrifugal Blowers


hot-air-recirculation-blowersdwdi-6Centrifugal Blowers making use of External Rotor Motors have wide applications in UPS, Control Panel, Railways, Rectifier, Blow Molding machines etc. Centrifugal Blower has high efficiency and low noise level, relatively small airflow with high static pressure. It is a space saving blower. These Centrifugal Blowers are available in either single or dual inlet. The single inlet external rotor motor is integrated in the impeller, which is mounted onto the side wall of the scroll housing. Dual Inlet Blowers have extremely low structured vibration rates.

Bag House/Pulsejet Filter

DSC01176baghouseA baghouse (B/H), aka fabric filter, is a particular air pollution control device, used in similar applications as electrostatic precipitators. In the 1970s, introduction of fabrics capable of withstanding high temperatures (> 350 degrees Fahrenheit) made baghouses practical for use in electrical generation and industrial processes. Baghouses are highly efficient particulate collection devices, regardless of the incoming dust loading or particle size. Baghouses also offer adaptability as dry collection devices using absorbents for removing gases and heavy metals.

As custom manufacturers of rotary airlock feeders; Prater-Sterling is dedicated to offering the highest-quality rotary airlock options to ensure the appropriate feeding, metering and control of materials.

Unit Dust Collectors

The filtering capacity is as high as 3-5 microns with an efficiency of 99%, which is in complete accordance with indoor air quality standards. They are energy efficient, easy to install and maintain with online reversejet cleaning of filters which ensures high efficiency. Since these systems are having cyclonic entry the bag life is much better and have the capability to handle high dust loads

Axial Flow Fans

AXIAL-FLOW-FANS2.189144301_stdAn axial compressor is typically made up of many alternating rows of rotating and stationary blades called rotors and stators, The first stationary row (which comes in front of the rotor) is typically called the inlet guide vanes or IGV. Each successive rotor-stator pair is called a compressor stage. Hence compressors with many blade rows are termed multistage compressors.

Buffing Dust Collector

Ashwa Buffing Dust CollectorThe objective of buffing is to make a rough surface smooth; however, every part does not have the same finish and will need to be worked differently. Buffing can be divided by three categories. They are defined as satin finishing, cut-down buffing for preliminary smoothness, and cut and color buffing for smoothness and luster.
