Sizing guide
How to size your dryer
- 1Take your compressor's free air delivery in l/min.
- 2Multiply it by factors F1, F2, F3 and F4 for your site conditions.
- 3Choose the first model whose rated flow is equal to or above the result.
Worked example
5,000 l/min at 8 bar (F1 1.05), 40 °C ambient (F2 0.79), 45 °C inlet (F3 0.67), 3 °C dew point (F4 1.00) → 5,000 x 1.05 x 0.79 x 0.67 x 1.00 = 2,777 l/min → PS 32.A.

| Value | ≤25 | 30 | 35 | 40 | 45 |
|---|---|---|---|---|---|
| Factor F2 | 1.00 | 0.95 | 0.88 | 0.79 | 0.68 |

|---|---|---|---|---|---|---|
| Factor F3 | 1.11 | 1.00 | 0.81 | 0.67 | 0.55 | 0.45 |

| Value | 3 | 5 | 7 | 10 |
|---|---|---|---|---|
| Factor F4 | 1.00 | 1.11 | 1.19 | 1.38 |
