Ventilation Cooling/ Heat Removal
GV is normally accomplished by roof or wall mounted exhaust or supply fans. Spaces such as manufacturing, warehousing, machine rooms, and vehicle services are typical applications. Area air change rates may be dictated by code requirements but more often exceed code minimums to insure elimination of orders and adequate dilution of fugitive emissions or provide combustion air. Fan serviceability and fan sound levels are often factors in equipment selection. Provision for make up air must be made for GV to function properly. Delivery of make up air, including entrance locations, cleanliness and conditioning for temperature or moisture content are important considerations.

Source capture intends to collect fumes, dust or other air borne material before it can escape to a wider area. Most Often utilized to keep contamination from worker breathing zone , it should be employed more often to reduce the need for more costly general ventilation. AIH provides excellent design practice guideline specifics on many source capture applications. After worker safety considerations system design should be focused on operating cost by good duct design and breaking apart of higher and lower pressure systems. Provisions for make up air MUST be made.,… Dust collection or filtration may be needed on exhausted air. Exhaust of Hazardous materials may require permission. Provision for make-up air must be made for Source capture systems to function properly. Make-up air quality must be considered if it processes; product or raw material might be affected. Delivery of make up air, including entrance locations, cleanliness and conditioning for temperature or moisture content are important considerations.

Scrubbers are typically tied to Source Capture Systems handling corrosive exhaust airstreams.
Fiberglass is the choice material for most of these systems, due to its performance in the environment. Fiberglass FRP construction is employs various specific materials and veils to provide protection for each individual application. FRP construction is limited to 200 Degrees F. Source Capture in series with scrubbers generally dictate centrifugal fans or pressure blowers.
