Safe Design, Low Operating Noise, Long Life. Environmentally Friendly Pump for the Next Generation

KRF04A / KRF08A

Continuous Degree of Vacuum
KRF04A: 55 kPa or lower
KRF08A: Recommended 60 kPa or lower (max. 75 kPa)
Continuous Degree of Exhaust Pressure
KRF04A: 50 kPa or lower
KRF08A: Recommended 60 kPa or lower (max. 75 kPa)
Flow Rate
75 to 155 L/min (60 Hz)
 Proven Design and Environmentally Friendly
CE Marking※ and RoHS Directive Compliant
Single-phase models and models without motors will not be compliant.
 Low Operating Noise
Noise-reducing design reduces noise by 2 to 5 dB (compared with our earlier models.)
 Long Lifespan
New blade material yields an increased lifespan of 20% (compared with our earlier models).

  1. Designed Pumping Capacity: Theoretical value based on volume. Refer to performance data for actual flow rate.
  2. Operation not allowed at ultimate vacuum. For model selection purposes only.
  3. Operable range of vacuum (exhaust pressure).
  4. '04 models are built-to-order items.
  5. Actual operating noise measured on a new pump with the ORION recommended motor running under normal and recommended vacuum/pressure conditions. Operating noise level is from a position of 1 m in front of the product and at a height of 1 m.
  • Operating environment (inlet air) conditions: air temp: 0 to 40 ℃, humidity: normal level (65±20%).
  • The allowable intermittent power supply voltage fluctuation range is ±10%, and the allowable sustained supply voltage fluctuation range is ±5% of the specified voltage.
  • Please install an overload protection device (such as a thermal relay).
