Duct smoke detector offer many advantages over conventional smoke detectors since they tend to be more sensitive to changes in the air. The detectors are also placed in the ducts where all the air circulates in a building, so they're more efficient. Here at Nearby Engineers , we offer the...
You can spot an automatic zone damper on duct work by noticing that there is an external motor mounted on the ducts in one or more locations. When heating or cooling are not needed in that building area or zone, the duct damper remains in the closed position. Our photo shows a commercial...
We include photographs of each type of damper or dampener used in buildings or in building mechanical systems and we provide links to in-depth articles describing the choices, installation, inspection, troubleshooting and repair of all types of building and HVAC system air controls, dampers and dam...
Fire dampers are used in air ducts of ventilation and air-conditioning system which has smokeproofing and fireproofing requirements, especially suitable for the important buildings that can not be reset manually. Installation Attentions 1. The valve body should be hoisted independently to prev...
