ACCESSORIZING AND

MODIFYINGYOUR

FILTEREDENCLOSURE

There are several ways to accessorize and modify the filtered enclosure for your individual requirements. These include the addition of accessory work surfaces, airflow monitors; exhaust transition kits, remote blowers, exhaust dampers, filters, storage cabinets and utility shelf kit.

1. Work Surfaces

An optional dished work surface is available to attach to the filtered enclosure.

Dished work surfaces are contoured to fit the dimensions of the filtered enclosures to contain spills. Epoxy is chemical resistant. See Figure 3-1for installation.

3. Exhaust Transition Kits for Ducting to Outside

Exhaust transition connects to the enclosures with integral motorized impellers from the top so the duct can be routed up and outside the building. The transition is available for 6" PVC duct. The transition should be sealed to the top of the enclosure with silicone sealant to prevent leaks. See Figure 3-3.
