Aerotech Components, Inc. was founded in 1993 and joined by it’s current CEO, Ralph G. Heysek. While being employed for 17 years with an air pump manufacturer that had dominated the aviation market from the early 1960’s, Ralph became an expert in aircraft pneumatic systems thru his FAA Certified Seminars and constant contact with customers, providing them with solutions to all their aircraft pneumatic system problems.
Inspired by customer comments and visions of the possibility of replacing out dated aircraft parts with new technology available in the 1990s, the CV1J4 “Clear View” Inline Air Filter was born.
With new technology come new partnerships. Aerotech Components, Inc. is proud to be an OEM supplier to another company that stands out in innovation and has a legacy of high performance for value; Mooney Airplane Company.
In October of 1995 Mooney Airplane Company began installing the CV1J4 “Clear View” Inline Filter in all model aircraft to prevent carbon dust contamination of the gyro instruments in the event of air pump failure.
Paying for a new air pump after it's failure may only be the beginning of more expensive problems you can prevent.
If you're the owner or pilot of a single engine aircrfat that employs vacuum gyro instruments this page is for you! Just in case you're not sure what is under the cowling, were talking single engine aircraft such as Cessna, Mooney, Piper and older Beech models.
Normal air flow during engine operation enters at the inlet air filter, ( usually under your injstrument panel), travels through the gyro instruments, through the vacuum regulator to the air pump inlet. Air pump exhaust (pressure side) is normally dumped into the engine compartment.
If pump failure occurs during engine operation, causing the pump coupling connector to separate, operation ceases immediately leaving the broken rotor, vanes and carbon dust within the pump. However, with vacuum still present in the gyro instruments and connecting lines, along with a positive pressure in the engine compartment, this carbon debris can be moved backward past the vacuum regulator and into both gyro instruments.

Next time you hear of someone replacing gyro instruments, take time to find out all the details. If carbon dust was found in the instruments...... The following items probably apply:
It was a single engine aircraft with vacuum gyros.
An air pump failed several flight hous prior.
It was not a late model Mooney aircraft.
Mooney Aircraft Corp. learned long ago that installing a filter between the air pump and vacuum regulator will prevent gyro instrument failure due to carbon dust contamination. All M20J, M20K, and M20M aircraft now leave the assembly line with CV1J4 " Clear View" inline filters installed for constant gyro protection
Air pump failures are unpredictable and expensive. Installation of an inline filter in vacuum gyro systems is a practical idea overlooked by most aircraft manufactures.
Gyro protection for Cessna and Piper single engine aircraft has just been made easier with installation of the CV1J4-C & CV1J4-P "Clear View" Inline Filter Kits. The only inline filter kits FAA-PMA approved for gyro protection on single engine aircraft.
A small price to pay for a product designed ( and proven ) to protect expensive gyro instruments.
