FFU is a type of unit used for filtering laminar air and supplying clean air. FFU can bu used standalone or installed modularly.
FFU is the core when making cleanroom equipment for a given space including clean booth, clean bench and cleanroom assembly.
Specification
• Low consumption, super performance and low operation cost Direct drive backward inclined fan, high efficiency, low noise, more endurable, more energy-saving.
• Scientific air passage design, low resistance, low noise, save space
• Flexible design to suit various needs We are equipment with great capabilities of customized design to suit various
needs. External size can be altered to suit various type of GRID. Also, we provide professional solutions in respond to changes of external material case, special power supply, or changes of fan configuration.
needs. External size can be altered to suit various type of GRID. Also, we provide professional solutions in respond to changes of external material case, special power supply, or changes of fan configuration.
• Safe and operation friendly FFU is able to support high-intensity box and ensures the safety of staff for installation and maintenance. Remote monitoring and adjustment are available and it is easy to operate.
• Muiti-level protective devices FFU is equipped with over-current relay, motor protective device, fault indicator and fault signal circuit. Thermal protector, fuse and motor breaker and such can be applied upon request.
