Overview

Engineering reference data for Compressed Air Receivers in miscellaneous.

Key Formulas

Unit Conversion

$y = x \cdot k$

Multiply by conversion factor.

Linear Interpolation

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

Percentage

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.

The receiver must be sized to handle the variation in consumption demand and the compressor's modulation strategy. A pressure differential ( $p_1 - p_2$ ) between the receiver's maximum and minimum operating pressures is essential for effective air storage and buffering. Operating the compressor at a pressure higher than the minimum process requirement creates this storage capacity.

Rule-of-Thumb Guidelines

Common industry rules for initial sizing estimates include:

1 gallon of receiver volume per 1 ACFM (Actual Cubic Feet per Minute) of compressor capacity.
4 gallons of receiver volume per compressor horsepower (hp).
