Note:

1. The output flow Nm³ is same to input air flow Nm³ after air purifier. Normally Nm³ means volume under standard conditions (0 deg C, 0.1013 MPa A). If the input dry air flow after purifier is supplied by buyer in Sm³ (20 deg C, 0.1013 MPa A), the output shall be adjusted to Sm³ technically and accordingly.

2. The performance is based on design basis of clause 1 in this technical annex.

3. Standard industrial performance tolerance: Output: + 4%      Purity: 0%
