Metal shell (chip, array type) muffler
This type of silencer consists of silencing elements, a metal outer shell frame, internal support components, and connecting components. The silencing elements and shell plates are modular and assembled on-site. They can be quickly disassembled and reassembled, making disassembly and assembly convenient and facilitating maintenance and repair.
Structure (chip-type, array-type) silencer
This type of silencer uses bolts to connect the silencing plates to the internal support, forming an integral structure. It can be assembled in a vertical shaft (vertical installation) or on a horizontal air duct (horizontal installation). The assembly process is simple and installation is convenient.
This type of silencer is an integral structure, composed of silencing plates, a metal shell, and flanges.
This valve can be electrically opened and closed, and the air volume can be adjusted.
Electric control valve is used to adjust the air volume of the branch pipe
The manual damper is used to adjust the air volume of the branch pipe, and can also be used for mixing adjustment of supply and return air.
It is normally on.
Fire dampers are installed at the end of ventilation and air conditioning systems with fire protection requirements.
Smoke exhaust valve (PYF, PYF-Y)
Manually or electrically opened for smoke exhaust in case of fire or when smoke exhaust is needed.
Smoke exhaust fire damper (PFHF, PFHF-Y)
Normally in the open state, it will close when the temperature of the flue gas inside the smoke exhaust pipe reaches 280℃ during a fire.
When ventilation is on, positive pressure causes the blades to open; when ventilation stops, the blades or counterweights close automatically due to gravity.
