HVAC ductwork includes pipe or closed conduits made of sheet metal, fiberglass board, or other suitable material for conducting air to and from an air handling unit

Industrial cooling systems and equipment includes air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers; ducts and/or pipes; and other devices for removing heat from a system that contains a heat source.

Energy recovery and heat recovery ventilators are mechanical exchange units that help reduce heating costs by retaining existing heat and optimizing the interior moisture content of the air.

Electro-pneumatic transducers convert current or voltage input signals to proportional output pressures. They are used as process control elements in valves, pneumatic relays, and flow regulators for applications such as spray and damper control

Vents and venting systems are individual products or complete systems that allow for the exchange of air from or within an enclosed area.

Pressure regulators are used to maintain a constant outlet pressure or flow

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only

IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices

IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch

Filter, regulator, lubricator (FRL) assemblies are pre-packaged or modular assemblies of common configurations of air filters, regulators, lubricators, and gauges

Shock absorbers, linear dampers, and dashpots provide motion damping in linear applications. They frequently incorporate fluid dampening, and can include mechanical or elastomeric elements

Integrated circuit (IC) linear voltage regulators use voltage-controlled sources to force a fixed voltage to appear at their output terminal

Dampers, diffusers, grilles and louvers are used to control and direct airflow in HVAC systems

Heating, ventilation and air conditioning (HVAC) chillers are refrigeration systems that provide cooling for industrial and commercial applications. They use water, oils or other fluids as refrigerants
