For special hood applications, including walk-in hoods, student hoods, or biological safety cabinets, we have a solution. Even if your older hoods have asbestos liners, we have a safe and non-hazardous solution for you. Call for details.
Each retro-fit kit is complete! There is no need to worry whether you have all the right parts.
There are two installation configurations. The standard Mark 3 configuration is a semi-flush mount that fits perfectly into the standard 2 ” x 3 ” rectangular cutout that you typically find on the corner post of the fume hood
If you do not have a cutout in this dimension, order the Mark 2 bracket kit that enables a simple surface mount installation. And the good news is that the Mark 2 mounting box is absolutely free with your purchase of a monitor!
Installation is easy. Dimensions, instructions, and technical support phone numbers are readily available if you wish to do it yourself. Most often, installation is performed in about half an hour per hood by in-house HVAC or facilities maintenance or engineering personnel. If you do not have access to such expertise, call us and we will refer you to a local CETA (Controlled Environment Testing Association) certified contractor.
