A human-powered air compressor driven by a bicycle-style pedal mechanism. Pedaling turns a flywheel through a chain/belt drive, which converts rotary motion into the reciprocating motion of a compressor crank. Air is drawn through a filter, compressed, and stored in a small receiver tank with a pressure gauge, relief valve, and check valve for safety. Ideal for off-grid workshops, rural use, labs, and emergency situations where electricity isn’t available.

Parts Used:

1. Pedal Drive Module: Crankset, bottom bracket, pedals, chainring, freewheel
2. Transmission: Roller chain or V-belt with selectable gear/pulley ratios
3. Flywheel: 2–6 kg for smoother pedaling and steadier airflow
4. Compressor Unit: 1-stage reciprocating compressor (single cylinder)
5. (Optional) 2-stage head for higher pressures with intercooler
6. Air Intake Filter/Silencer: Dust protection and noise reduction
7. Receiver Tank: 5–15 L with drain cock
8. Valves & Safety:
9. Non-return (check) valve to isolate tank
10. Pressure relief valve (factory set)
11. Unloader valve (optional, eases restart under pressure)
12. Instrumentation: Pressure gauge (0–10 bar), optional flow indicator
13. Frame & Mounts: Welded MS frame, compressor base, guards for chain/belt
14. Hose & Fittings: Quick coupler, PTFE tape, safety clips
15. Cooling: Finned tube or simple air-blast guard over head/cylinder
16. Optional Add-ons: Regulator + moisture trap, small tool kit, tachometer (RPM)
