How do I size an air receiver tank?

Use V = Q × t × P_atm / (P_max − P_min), where Q is air demand (L/s), t is acceptable time between compressor cycles (s), P_atm is atmospheric pressure, P_max is cut-out pressure, and P_min is cut-in pressure.

What is the rule of thumb for air receiver sizing?

A common rule of thumb is 3–5 gallons of receiver per CFM of compressor output, or roughly 10–20 liters per L/s. This provides a buffer for short-term demand peaks.

What is cut-in and cut-out pressure?

Cut-out pressure is the maximum pressure at which the compressor stops. Cut-in pressure is the minimum pressure at which it restarts. The difference (P_max − P_min) is the pressure band, typically 1–2 bar.

Why do I need an air receiver?

Air receivers smooth out pulsations from the compressor, store energy for peak demands, allow condensate to drop out, reduce compressor cycling, and act as a buffer between supply and demand.

Can I use multiple air receivers?

Yes, using a wet receiver (before dryer) and dry receiver (after dryer) is a best practice. The wet receiver handles pulsations and condensate, while the dry receiver provides clean, dry air storage close to the demand.

रिसीव्हर आयतन सूत्र

V — रिसीव्हर आयतन (litres)
Q — हवेची मागणी (वायुमंडलीय दाबावर L/s)
t — अनुमत दाब घट वेळ (seconds)
P_atm — वायुमंडलीय दाब (1.013 bar abs)
P_max — कट-आउट दाब (bar gauge)
P_min — कट-इन दाब (bar gauge)

उदाहरण — मध्यम कार्यशाळा

Given: Q = 15 L/s, t = 30 s, P_max = 8 bar, P_min = 6 bar

V = 15 × 30 × 1.013 / (8 − 6) = 227.9 litres

मानक 250 L रिसीव्हर टँक निवडा.

⚠️ Note: नेहमी पुढील मानक टँक आकारापर्यंत राउंड अप करा. भविष्यातील विस्तारासाठी 10–20% मार्जिन जोडण्याचा विचार करा.
