BLOCKAGE PREVENTION SYSTEM

Frequently Asked Questions

The Airguard BPS circulates the hydraulic oil through a radiator that’s mounted to the fan housing intake of the air seeder cart. We tap into the Return side of the fan motor, therefore we do not take hydraulic power from running the air seeder unit. We extract the heat before the oil gets returned back to the tractor, increasing the life of the oil. By heating up the air the BPS prevents condensation and reduces buildup on all internal components, and at the same time cools the oil.

No. There is not enough time to dry out the product if it’s already damp. It will, however, eliminate any future moisture to be drawn into the system. The warmer air allows the meters to operate more efficiently. And the hoses, manifolds and openers are warming from the inside. After putting on the BPS, you can immediately feel the difference in the temperature of the hoses under the cart. Since all the parts are physically warmer, dusty fertilizer, mixed with humidity that’s constantly being drawn in, will not have a cold surface to build up on. Everything flows better through to the discharge at the opener.

The Airguard Blockage Prevention System has a series of valves that help regulate the pressure in the fan circuit when the return line pressure gets too high. If the return pressure goes above 750psi the fan pressure will be reduced until the return pressure goes below 750psi. There is also another pressure relief that is set to 850psi and will relieve to the case drain if the pressure goes above 850psi. All of this is done automatically and no setting of the system is required.

Our aluminum radiator cores are pressure rated to 2400psi to ensure that your investment is protected.

We designed our snorkel kits to help reduce maintenance on the BP System. Using a snorkel kit moves the air intake to the top of the cart thereby allowing the fan to suck in clean air. This reduces the amount of dust and debris that the fan sucks in, which helps to keep the radiator fins clean. It also helps to keep the internal parts of the air system clean and reduces plugging issues.

The single snorkel is designed for smaller fans, mainly the Crary 6″ Fan. The dual snorkel is designed for higher flow fans which is most of the fans on air seeders. The dual snorkel ensures that fan air flow is not restricted by using 2 – 8″ hoses for the air intake.

Yes you can. If customers are not having issues with oil that is overheating, or with humidity problems, but the air intake on the fan is often plugging up with straw and chaff, the snorkel is a great alternative. Various air seeders have the air intakes low to the ground and close to the tires. The snorkel alone can eliminate some of the problems that come with that. The cost is very economical. If you choose to add the BPS radiator at a later time, you can.

It depends on where the issues with the operation are:

  1. Fertilizer dust buildup issues due to humidity: Recommend installing BPS on the fertilizer fan.
  2. Seed treatment coming off the seed: Recommend installing BPS on the seed fan.
  3. Need to cool hydraulic oil: Recommend installing BPS on the fan that is easiest to access.
  4. Issues on both the seed and fertilizer lines: Recommend installing BPS on both fans.
  5. If the fans both supply the same plenum then you will need to install BPS on both in order to heat up the air stream sufficiently to make a difference.

It’s compact in size and simple to install. It has a superior performance pressure rating. Is equipped with a dual pass aluminum core which takes 10-15% more heat out of the oil, compared to a single core unit. We successfully regulate the hydraulic oil pressure when spikes or blocks occur. Competitors’ systems may discharge oil to the ground during operations or burst.

V1 – The relief valve MUST be set at the beginning of each seeding season. See STEP 12 in the V1 manual.

V2 – Other than cleaning there is no maintenance required.
