How this is calculated
The volume shown is the larger of two calculations.
- Limiting starts: the usual air receiver formula, V = 0.25 × Q × p₀ / (f × Δp), where Q is the compressor flow, p₀ the atmospheric pressure (1.013 bar), f the maximum number of cycles per hour (60 for a screw compressor, 20 for a piston compressor) and Δp the difference between cut-out and cut-in pressure.
- Absorbing peaks: when the tools used at the same time consume more than the compressor produces, the receiver supplies the difference during the peak: V = (peak Q − compressor Q) × duration × p₀ / Δp.
Peak consumption adds up the most air-hungry tools, as many as there are people working at the same time. Average consumption counts continuous-use tools (sanders, spray guns) in full and intermittent tools at half, with a margin for leaks. The working pressure is that of the most demanding tool, plus 1 bar for network losses.
The volume of the built-in receiver (K series, E series, M series) is deducted. The rest is rounded up to 1,000 L vertical receivers, the capacity of our receivers.
Does a bigger receiver use more energy?
No. A bigger receiver does not use more electricity: it spaces out compressor starts, stabilises the pressure at the tools and lets condensate settle before the network. However, it does not make up for an undersized compressor: if your tools use more air on average than the compressor produces, the pressure will always end up dropping.
Painted or galvanised?
The painted receiver is the most economical choice when a dryer is installed before the receiver: the air entering it is already dry. The hot-dip galvanised receiver, inside and out, resists corrosion even with humid air: it is the right choice without an upstream dryer, in a humid workshop or under an outdoor shelter. Both come in 10 and 13 bar: choose a working pressure at least equal to that of your compressor.
