When a compressor takes a long time to fill, doesn't reach cut-out pressure or the pump overheats, the valve plate is usually the culprit. With this valve plate kit you replace the damaged part and the compressor regains its normal air flow and working temperature.
It is the spare for the AP1100 (PRO103 compressor) and AP1500 (PRO104 and PRO204 compressors) oil-free silent pumps. A simple, inexpensive repair that saves replacing the whole pump.
The reeds on the plate work thousands of times a minute and, over time or with dirt in the intake, lose their seal: replacing them is the quickest way to restore the compressor's performance.
✅ Key benefits
Restores air flow: the tank fills at its normal rate again.
Lower temperature: the pump stops overheating.
Two versions: AP1100 and AP1500.
Inexpensive repair: without replacing the whole pump.
Oil-free pumps: specific to silent units.
🏗️ What it's for
Repairing AP1100 pumps on the PRO103.
Repairing AP1500 pumps on the PRO104 and PRO204.
Compressors that don't reach cut-out pressure.
Maintenance of silent compressors.
📋 Technical specifications
AP1100: for PRO103 compressor
AP1500: for PRO104 and PRO204 compressors
Pump type: silent, oil-free
Contents: valve plate kit
💡 Vetonek tip: replace the valve plate with the compressor disconnected and the tank empty, clean the cylinder head seat thoroughly and tighten the bolts in a cross pattern, gradually. Also check the intake filter: dirt damages the valves.
Frequently asked questions
When does the valve plate need replacing?
If the compressor loses air flow, is slow to fill the tank or doesn't reach cut-out pressure, while the motor runs normally.
Which one do I need?
The AP1100 for the PRO103 and the AP1500 for the PRO104 and PRO204.
Why does the pump overheat?
A valve plate that doesn't close properly causes the air to be recompressed and the pump runs hotter.
What else should I check?
The piston ring and seals, the connecting rod and the intake filter.
Can I fit it myself?
With mechanical experience, yes: disconnect the compressor, drain the tank and tighten the bolts in a cross pattern when fitting.
