Calculate filter bag differential pressure

Enter simultaneous upstream and downstream readings in the same unit. This calculator subtracts downstream pressure from upstream pressure and converts the result.

Pressure readings

Upstream pressure Downstream pressure

Units

Unit for both readings Result unit

Each reading must be non-negative and no greater than 10,000 kPa (100 bar; approximately 1,450.38 psi). This is a software input limit, not a product pressure rating.

Upstream minus downstream

Conversion basis: 1 bar = 100 kPa; 1 psi = 6.894757293168 kPa. Results are rounded to six decimal places. This calculation does not set a bag-change threshold or confirm safe operating pressure. Use the limits and change criteria for your specific bag, housing and process.
