Our premium grade D33 model is made to help silence your noise problems on such applications as rotary positive displacement blowers. Our D33T model still offers the same premium silencing as our D33 model but can be built with a nozzle configuration to better suit each application.

For standard silencing at blower speeds above transition speed.

A multi-chamber silencer containing a high frequency absorption device in addition to a special arrangement of volumes and air passageways to effectively reduce both pulsation and excessive high frequencies through the process of converting noise energy into heat. These units may be installed horizontally or vertically. The D33T units are normally installed vertically. Design parameters permit nozzle orientation to suit installation requirements.

All welded steel sheet and plate construction for long service life. Acoustic absorption material temperature limits far exceed application temperatures. Exterior surfaces are prime coated. Flanges are drilled to match 125lb American Standard Flanges. Inspection openings, mounting brackets, relief valve nozzles or special paint are available at extra charge.
