Bautz Engineering's AeroFid° family of Micro Leak Detection Systems for filled aerosol cans offers a time proven, very reliable, economical and practical solution to achieve immediate production savings and improved safety and quality by eliminating bubble detectors and water bath operators. In addition, the complementary water bath test method with partially submersed cans generates accurate data to be easily and consistently gathered as an integral part of a quality management system like ISO 9000 or similar to force improvements in quality and the supply chain.
The AeroFid°60 Micro Leak Detector fully complies with the recent European EN 60079 Aerosol Directive and with current United Nations Standards to detect micro leaks in filled aerosol cans as low as, and/or lower than 2X10-3 mbar/sec. When combined with a test system for empty cans, the AeroFid* leak detector can be an alternative to the traditional immersion test.
The AeroFid°60 has the smallest footprint in the industry for high speed aerosol can micro leak detectors. This compact, „over the conveyor“ machine houses the high speed leak sensor, the control panel with touch screen display and the purifying air generator. Our long standing, fast responding Model 22B hydrocarbon propellant sensor automatically extracts one sample at a time from the head and valve area of each individual aerosol can. Jam controlled by a star wheel or feed worm, the cans freely scroll through sensing area. Immediately after a leak was detected, the faulty can is rejected from the conveyor. For speeds above 60 CPM, per minute our AeroFid°100, AeroFid°200 or AeroFid°500 should be considered.
The AeroFid°60 s a fast responding automatic leak detector for filled aerosol cans using our decade long, time proven, standard ionization technology in a compact rack mount sensing module. The very fast responding leak analyzer extracts a sample from the head and valve area of an aerosol can with a regulated gas flow of a few liters per minute. The extracted gas from the leak is finely filtered and directed to the detector via a high precision toggling device and a metering module. The sample conditioner is designed to rinse the entire system after a leak occurred at every half step between detecting the aerosol cans to rinse the entire system including the probe tip with zero gas. Aerosol spray cans with propellants like propane/butane, or other hydrocarbons and/or hydrocarbon mixtures or HFA may have micro leaks as low as, or lower than 2X10-3 mbar.l.s-1.. Looking for such small leaks as specified in recent UN / FEA regulations is very difficult or impossible when the bubble detection method in a conventional water bath is used.
Once a leaking can reaches the sensing area, leaking gas is extracted into the detector. As soon as the leak concentration is measured, the stored data are used to reject the leaking can from the conveyor into a safe container. The various AeroFid° leak testers are capable to detect from over 80 to up to 500 cans per minute.
Our leak testers for filled aerosol cans with hydrocarbon propellants are successfully used daily 24/7 for over 27 years
