Connect diffusers to duct.
No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.
Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.
Control the flow of air and material through duct systems.
More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.
Use in dust collection systems. The slide pushes through the top of the gate to clear debris.
Often added to existing systems, these gates install without disassembling duct. Also known as half gates.
Regulate airflow by adjusting dampers from fully open to fully closed.
Save energy and increase comfort by heating and cooling only the areas that need it.
Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.
In the event of a fire, these dampers automatically stop airflow through duct.
For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.
Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.
Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.
Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers.
Also known as thermodynamic steam traps, these discharge condensate when close to steam temperature for minimal energy loss.
When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments.
Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.
Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines.
These steam traps offer good corrosion resistance.
Vent air from your enclosure to equalize pressure and stop condensation from forming inside while securing cords in wet environments. These polyamide grips are lightweight and resist rusting.
Secure cable installed through enclosures in wet environments while venting air to protect electronics from condensation.
Body is brass.
These valves are made of corrosion-resistant materials for use in wet conditions and harsh environments.
For excellent corrosion resistance in wet conditions and harsh environments, these valves have no metal parts.
An internal wire brush traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet.
Turn the key to manually vent radiators and heaters.
Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port.
Use this valve with oil, diesel fuel, gasoline, and kerosene.
Eliminate air pockets in your drinking water system with these valves. They meet NSF/ANSI 61, which designates them as safe to use with drinking water.
Less than a quarter of the height of standard pressure-relief valves, these are often installed on tanks in low-clearance areas.
Cleaned and bagged for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen.
The most basic option for air and inert gas applications.
Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.
Attach a pressure gauge to the 1/4 NPT female port on these valves.
Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.
For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.
