Ensuring a smooth startup for your Airguard Blockage Prevention System (BPS) is critical to maximizing performance and longevity.

This mandatory process prevents air pockets, optimizes hydraulic flow, and ensures seamless operation.

Failure to follow these steps can lead to system inefficiencies, costly downtime, and potential equipment damage. Follow this step-by-step guide carefully to ensure your system runs at peak performance before starting your season.

Step-by-Step Startup Procedure – A CRITICAL Process

Step 1

After you have installed the Airguard Blockage Prevention System, it’s absolutely critical that you start the Aircart fans very slowly. You’re introducing an air pocket that must be moved slowly to the tractor while you prime the hydraulic core with oil. This process ensures all fittings are sealed and secure.

Step 2

Get your oil warmed to 100°F. Skipping this step can cause serious operational issues. Cold oil has high viscosity and will not move through the internal components easily. By warming the oil first, everything will operate as it should.

Step 3

Initiate your fans with 500 Fan RPM at 25% oil flow (or 10% of your max fan speed). If everything looks good, the pressure is just starting to register on the Airguard pressure gauge. If all your fittings are holding their seal, continue to the next step. If your fan is NOT moving, that’s okay—the oil is circulating. Operate this way for 10 minutes.

⚠️ CRITICAL NOTE: If there is a pressure spike at this low oil flow rate, there is potential for an air lock. Disconnect the end fitting on the Return Line at the SCV and drain off some oil to release the pressure. Reconnect the end fitting and repeat Step 2.

Step 4

Run 1000 Fan RPM at 45% oil flow (or 35% of your max fan speed). Operate for 5 seconds.

Step 5

Run 2000 Fan RPM at 65% oil flow (or 75% of your max fan speed). Operate for 5 seconds.

Step 6

Run 3500 Fan RPM at 85% oil flow (or 100% of your max fan speed). Operate for 3-5 minutes.

Take time to ensure that your conveyor or auger is working properly in conjunction with your Airguard kit. Turn your fan RPM down to 50% oil flow and engage the conveyor/auger. If everything is operating as it should, you have successfully installed your Airguard Blockage Prevention System kit. If there are any questions or concerns about the operations, call your Airguard Sales Representative IMMEDIATELY.

Ongoing Best Practices – Protect Your Investment

This startup procedure is NOT optional. It must be performed at the beginning of each season to prevent air pockets and leaks after seasonal temperature shifts.

Maintain regular system checks to ensure continued efficiency and peak performance.

If you experience ANY issues, do not hesitate to contact your Airguard support team.

How Does the Airguard Blockage Prevention System Work?

The Airguard BPS optimizes hydraulic efficiency by circulating oil through a radiator mounted to the fan housing intake of the air seeder cart. By tapping into the Return side of the fan motor, we avoid drawing power away from the air seeder.

This process extracts heat before oil returns to the tractor, extending oil life while also warming intake air to prevent condensation and reduce internal buildup.

The result? Improved efficiency, reduced maintenance, and better overall performance.
