Industrial Ventilation

Gravity ventilation, louvers, wind powered roof exhauster's, ridge vents and low profile gravity vents.  Panel fans, axial fans, utility sets and OEM fans.  Gas fired Air Make-Up systems.  Gas fired Air Rotation systems.  Industrial ventilation fans are available in choice of metals and fiberglass.   We are expert in gravity ventilation of large industrial buildings without using power.  Gravity systems rely on thermal draft to ventilate large heat producing buildings including forges, foundries, steel mills, paper mills, glass plants and other similar buildings.  Large mono-vent, ridge ventilators are typically used in glass manufacturing plants and major forge operations at the roof peak to exhaust warm air.  Louvers on building sidewall allow fresh air ingress.  Powered wall fans provide supplemental fresh air to compliment the “Moffitt Pressure-Gravity System.”

Moffitt wind-powered roof ventilators eliminate use of electric motors for roof ventilation requirements.  Most industrial facilities require roof level exhaust and side-wall air intake.  Moffitt can provide this ventilation without using power: no electric motors or wiring to the roof area.  Ventilate your building without using electricity with Moffitt GreenRoo “wind-powered” roof ventilators and Moffitt side-wall louvers and save on maintenance and utilities.  Moffitt does provide electric wall mounted, supply fans to supplement the non-powered system by injecting outside air to areas of the facility that benefit from addition air in the warm seasons.

We rebuild and service all gravity ridge ventilators including Robertson and Moffitt.  Moffitt designs cutting edge industrial ventilation systems using CFD modeling of the entire steel mill or glass plant to verify flows and temperatures.  Moffitt can provide “Pressure-Gravity” ventilation systems for most major industrial facilities.
