Greenheck Lab Exhaust Fans Receive High Wind Certification

Greenheck’s Vektor-H and Vektor-HS laboratory exhaust fan systems have received Miami-Dade NOA Certification and Florida Product Approval. The Vektor-H high plume fan with fixed discharge nozzle and the Vektor-HS high plume fan with variable geometry nozzle are the industry’s first laboratory exhaust fan systems to be certified to high wind standards. Both have been tested and approved in accordance with TAS 201: Large Missile Impact, TAS 202: Uniform Static Pressure and ASTM E72 (modified) for wind-borne debris regions up to 140 PSF. Advantages of NOA Certification include quicker project approval; no special enclosures needed around the lab exhaust system to meet construction requirements; and reduced building first-cost by eliminating unnecessary duct runs to these enclosures. NOA Certification is available on 1x1, 2x1 and 3x1 systems and fan sizes 9 through 36.

Greenheck, the worldwide leader in manufacturing and distributing air movement and control equipment, offers the industry’s widest selection of lab exhaust systems to meet any application requirement.
