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.

Fórmula del volumen del calderín

V — volumen del calderín (litros)
Q — demanda de aire (L/s a presión atmosférica)
t — tiempo admisible de caída de presión (segundos)
P_atm — presión atmosférica (1.013 bar abs)
P_max — presión de corte superior (bar manométrico)
P_min — presión de corte inferior (bar manométrico)

Ejemplo — Taller mediano

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

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

Seleccione un calderín estándar de 250 L.

⚠️ Nota: Redondee siempre hacia arriba al siguiente tamaño estándar de tanque. Considere agregar un margen del 10–20 % para expansiones futuras.
