  • *1This product is for dry air. Use in clean air and take care that drain and oil content do not get into this product.
  • *2Use dry air when operating at low temperatures and with no condensation.
  • *3Manual operation is available for DIN terminal type only.
  • *4Vibration resistance: No malfunction occurred in 1 sweep test between 8.3 and 2,000 Hz. The test was performed in both energized and de-energized states in the axial and right angle directions of the main valve/armature. (Initial value)
    Impact resistance: No malfunctions after testing using a drop-type impact tester under the following conditions: in the axial direction and at a right angle to the main valve and armature in both energized and non-energized states (once for each condition state). (Initial value)
  • *5DIN terminal type supports dust-proof and blow-proof (IP65) performance.
