The Fire and Ceiling Radiation Dampers Product Catalog is a complete listing of the manufacturer’s full line of fire dampers and ceiling radiation dampers for use whenever air distribution system ductwork penetrates fire-rated barriers.

A line of Auto-Draft® RT Series rooftop inducers have a constant operating pressure (COP) control. The COP control delivers precise draft or exhaust by modulating fan speed to deliver a constant negative pressure within a chimney or chase as draft requirements or exhaust loads change.

The WhisperRecessed™ ventilation fan is an 80-cfm fan-light combination that is recessed into the ceiling offering quiet, energy-efficient, and powerful ventilation. The Energy Star®-rated compact fluorescent lamp provides diffused, uniform illumination with the 18-W CFL bulb.

Remote testing capability has been added to the updated Series DNR and watertight NEMA DNRW InnovairFlex™ intelligent duct smoke detector housing with the intelligent Remote Test Capable® photoelectric detector (2251BR). This optional detector is especially designed for use in applications requiring a remote test.

A 24-page catalog showcases the manufacturer’s line of heavy-duty and industrial dampers. Control, round control, isolation, backdraft, pressure relief, tunnel ventilation, smoke and blast, and bubble tight damper models are detailed.

With the ability to operate as a standalone system or be integrated with a building automation system, the MatrixMonitor™ is a digital instrument that gauges airflow in fan arrays containing three to 98 fans, with maximum airflow of 300,000 cfm per array.

Most new installations of grilles and diffusers involve a suspended ceiling grid, but some installations require surface mounting. Square ceiling diffusers and filter grilles can present the biggest challenge. Here are some recommended guidelines and solutions.

Although the project had to be redesigned more than once, the Almost Home Animal Shelter in Fort Dodge, Iowa, has now been efficiently operating for more than a year with a dedicated outdoor air system (DOAS) and an integral energy recovery wheel.

Manufactured from a durable polyester material, PolyArmor™ duct liner is fiberglass-free and won’t irritate the skin, the company said. The polyester material is webbed into a thermal blanket, which is then bonded with a Foil-Scrim-Kraft (FSK) facing to resist damage during system installation and operation.

The TapeMaster™ HVAC-TAPE2 is a 2-inch aluminum foil tape dispenser. It is engineered to remove the paper release liner from foil tapes with ease. The tape dispenser conveniently rolls the waste paper onto a take-up reel for easy disposal, eliminating little pieces of scrap from the jobsite, the company said.
