To understand the operation of combustion air openings, it’s a good idea to review some airflow basics. For airflow to move through a duct, there must be a pressure difference across it created by an external source. Traditional installations depend on natural forces to create this pressure difference.
The NEWS’ 2017 Dealer Design Award gold-winning Testing & Monitoring product, the AVUL Air Velocity Transmitter from Dwyer Instruments Inc., was designed to quickly and accurately measure air velocity or volumetric air flow in variable air volume (VAV) units, HVAC ducts, fume hood exhausts, and/or air-handler units.
ProForm F3 Harnesses feature a patented relief cord system that allows users to relieve possible deadly pressure on femoral arteries and pressure on the clavicle typically caused by harness straps in a post-fall condition.
The Die Cast Pocket Level with 360-degree Locking Vial features amplified rare Earth magnet technology. It utilizes magnetic circuits to redirect and focus the magnetic field for holding power. Providing functionality similar to a protractor, a Locking 360-degree Adjustable Vial secures the vial in place, so users can identify and repeat any angle needed.
Force5 HVAC spray works as a corrosion inhibiter, lubricant, and cleaner to protect heat exchange fins and cooling coils to keep them in good working order. HVAC condenser and evaporator fins, made of aluminum or copper, may corrode in humid or moist settings, particularly in high-salt environments near the coast.
