Belt drive, built to be serviced
The KRSB is Kaishan's belt-driven rotary screw line, from 5 to 50 HP. The belt drive with automatic tensioning keeps power loss low and makes the drive easy to service, while Kaishan's SKK airend — with an asymmetric 5/6 rotor profile and precision-ground rotors — delivers 16 to 212 CFM at 125 PSI.
Order it base mounted (KRSB), or as a KRST on a 120 gallon receiver — with or without an integrated refrigerated dryer and coalescing filter. An oversized dryer option is available on 7.5–25 HP tank units.
Standard on every KRSB
- Belt drive with automatic tensioning
- IE3 premium efficiency motor
- Integrated aftercooler & cooling fan
- Digital control panel
- Load / unload controls
- Sound-deadening enclosure
- High-efficiency intake filters
- 316 stainless control tubing
