Laminar Flow A low-profile deep sink design suitable for working with open dishes but also may be used with the etch chemical within the sink, using the additional drain valve to decant back to a container.
Extraction at high velocity through the slots at the back, into a plenum chamber which enables a duct connection either from the top or from below, creates air movement over the open trays of etchant, away from the worker.
A cold water tap, with 1/2" hose adaptor, is provided in each compartment

Fan and Extraction Duct Systems
Centrifugal Fans - the motor being out of the air-stream - constructed in chemical resistant Polypropylene, are employed with the duct system in rigid PVC to remove the fumes.
Centrifugal Fan The price of the units (as Coded above) includes provision for a fan. Duct systems must be designed to suit the location of each installation and the fan specification may need to be uprated.
We can quote for installation of the duct system or supply the the units without the fan for others to install.
