This amount should not exceed 4.4 L/min (ANR) for IR1000/2000 series regulators and 11.5 L/min (ANR) for IR3000 series regulators.
For new IR1000-A/2000-A/3000-A series regulators, 1 L/min (ANR) is the max. amount.
Check to confirm whether the leakage is actually bleed air before taking any further steps.

The old IT1000/2000/IT4000 series, however, can be ordered for maintenance purposes (as of May 2021).
Despite this, we recommend replacing any old products with a current ITV1000/2000/3000 series product.
Note) If the input signal of the old IT series product was a 2-wire type current type, only 4 to 20 mADC signal wiring was required, with power supply wiring not required.
