The CMD airlock is ideal for applications where dry raw or finished products are being handled in the process and where inspection or system clean-out are required. Because the CMD is designed for high process rates and possesses features suited for sanitary processes, the airlock is ideal for food and pet food applications.

The CMD is also a direct replacement for traditional square inlet Schenck Process MD airlocks in plant applications where sanitary requirements have increased, but the existing system does not allow for the use of a round inlet airlock. 

Three different sized models of the CMD each come equipped with a square inlet and outlet, along with seals and product contact surfaces that meet food safety requirements. The CMD is designed with a rail system consisting of externally mounted precision shafts that are fixed to the tail side endplate on one end and are supported by special composite linear bearings pressed into the valve housing on the other. The endplate/rotor assembly can be unbolted from the housing, and the assembly can be pulled from the housing and drive coupling while remaining rigid to the housing via the rail system. These features simplify removal and provide access to the internal valve cavity, rotor pockets, and all other product contact areas for quick and easy cleaning.

Other key features of the CMD Airlock include:

* Easy access to seals with rotor removed from endplate
* All stainless steel construction--with the exception of the endplate bearings
* Close clearance design reduces overall leakage through the valve and minimizes pneumatic system losses.
* Maximum 32 Ra finish on all wetted (product contact) parts
