No. Compatibility depends on the specific compressor model, tank capacity, mounting configuration, and system design. Always verify your model number and parts information before purchasing.

Why is my Rolair air compressor tank losing pressure quickly?

Rapid pressure loss is usually caused by leaking fittings, a faulty check valve, or air escaping through worn seals. Inspecting all connection points on the tank assembly typically identifies the source.

Can I install the air compressor tank myself?

Installation can be performed by users familiar with compressor systems. The process involves depressurizing the system, disconnecting existing lines, and securely mounting and sealing the replacement tank.

What is the purpose of the Rolair TNKASY5715K17 air compressor tank?

The tank stores compressed air generated by the compressor pump, helping maintain steady pressure output and reducing motor cycling frequency. It ensures consistent airflow delivery for air tools and compressor systems.

Troubleshooting

The Rolair TNKASY5715K17 Air Compressor Tank is a replacement or service tank assembly used in compatible Rolair air compressor systems to store and regulate compressed air. When issues appear, they typically affect pressure stability, air delivery consistency, and overall compressor cycle performance.

Common Issues:

Air leaks around tank weld points or fittings.
Rapid pressure loss after compressor shutdown.
Excess moisture accumulation inside the tank.
Compressor short-cycling due to pressure instability.
Restricted airflow from outlet or drain port blockages.

Air Leak from Tank Fittings or Seams.

Quick Check: Spray soapy water around inlet/outlet fittings and welded seams while tank is pressurized.

Fix Suggestion: Tighten threaded fittings or replace faulty valves. If leakage is from welded areas, tank replacement is required.

Prevention Tip: Avoid over-torquing fittings during installation and inspect connection points during routine maintenance.

Rapid Pressure Drop After Shutdown.

Quick Check: Observe pressure gauge after compressor stops and note any quick decline.

Fix Suggestion: Inspect check valve and tank fittings connected to the Rolair TNKASY5715K17 assembly for backflow leakage.

Prevention Tip: Clean and service the check valve regularly to maintain proper sealing performance.

Excess Water Accumulation Inside Tank.

Quick Check: Open the tank drain valve and check for excessive water discharge or rust-colored moisture.

Fix Suggestion: Fully drain the tank and ensure the drain valve is functioning correctly without obstruction.

Prevention Tip: Drain moisture daily in humid environments to prevent internal corrosion.

Compressor Short Cycling Frequently.

Quick Check: Monitor compressor start/stop cycles and compare against normal operating intervals.

Fix Suggestion: Inspect pressure switch calibration and ensure the tank is not leaking or undersized for the compressor system.

Prevention Tip: Maintain correct pressure switch settings and ensure compatible compressor pairing with this tank model.

Customer Experience: The TNKASY5715K17 tank was installed after the original tank developed a pressure retention issue. Following replacement, the compressor maintained air pressure more consistently, operated with fewer start-stop cycles, and returned to reliable daily use.
