Towel Guard
The towel guards are located under the work surface at the bottom rear and sides of the return-air plenums.
Acting as a protective screen, integral to the interior walls, they help prevent wipes and other paper materials
from being drawn into the blower system. They need to be kept clean at all times.
Work Surface
The work surface is constructed of corrosion resistant stainless steel. This surface is finished to reduce light
reflection. It is also recessed to retain spills. The work surface and work surface supports are removable
allowing access to the drain pan.
Drain Pan
The drain pan is constructed of corrosion resistant, stainless steel. The drain pan is designed with a smooth
radius along all four bottom corners to facilitate cleaning and disinfection. Drainage is provided by a stainless
steel ball valve located on the underside of the drain pan.
View Screen
The cabinet view screen is constructed of UV resistant safety plate glass. It is designed to move vertically to
allow access to the work area and it is counterbalanced for ease of movement. The proper work access opening
is clearly marked with arrows on each side of the view screen and the position of the view screen is monitored
by an optical sensor activating the sash alarm when not properly positioned.
