The 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.

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.

A baghouse (BH), 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.

Centrifugal 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.

Our collectors are compact and mobile (on wheels) with low noise level suitable for a wide range of indoor applications. 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
