Pumps & Compressors
Nitto Kohki
Nitto Kohki pumps and compressors deliver oil-free - and therefore oil-mist-free - compressed air and vacuum for demanding applications. The range comprises AC piston compressors (AC0xxx series, 230 V/50 Hz), DC compressors (DAH, 12/24 V DC) and DC diaphragm pumps (DP0xxx, 12/24 V DC) for flow rates from a few up to around 80 l/min at pressures up to about 7 bar.
The oil-free design ensures clean, contamination-free delivery of air and gases - essential for medical, laboratory and analytical technology. Compact dimensions, quiet running and low-maintenance diaphragm or piston mechanisms allow easy integration into devices and systems; the DC variants are also suited to mobile and battery-powered use.
