Gas Blending

An essential part of safe diving is the quality of the air or other gas mixtures we breathe.
This is also something that should not be left to chance or guesswork.. From the earliest days of ANDI the importance of this was recognized and through the pioneering work of Ed Betts, the founder of ANDI, came several industry firsts in this area.

Among these are:
The first breathing gas purity standards for gases other than air.
The first gas blending and oxygen handling text.
The first equipment servicing procedures for oxygen and EAN equipment.Our standards for breathing air are also the highest in the industry.In addition to the many courses we offer in the use of air, SafeAir and trimix for diving we also offer courses in Gas Blending and Equipment Servicing which are the most comprehensive in the industry.ANDI Philippines can also provide our facilities and customers with the hardware needed to filter air to ANDI standards as well as for the blending of SafeAir or trimix through the use of partial pressure or other blending techniques.

We offer custom designed gas blending whips made with either brass or stainless steel with a variety of choices for fittings, gauges, hoses and filling adapters. All our whips are made with quality hardware appropriately rated for the intended pressures to be used. Our blending gauges are available with accuracy ranging from 1% to 0.1% depending on the specific application and customer needs. They are also available in either bar, PSI or a combination of both in easy to read dials. We also offer digital gauges in either bar or PSI.As for our filtration hardware, we offer compact 15" filter housings or 32" housings plus a combination coalesor/ filter combination housing which is 24" tall. Different composition filtration media are also available in pre-packed cartridges such as alumina, 13X and tripack ( 13X-Hopcalite-Activated Charcoal ). We also offer re-packable cartridges and bulk filtration media for use with them.Blending panels, manifolds and Haskel pumps are also available.All hardware is tested prior to delivery and backed with a 1 year warrantee on parts and labor.Contact us for all your gas blending and air filtration requirements. We can also test the air from the filtration system so you can be confident of the quality of the air from these systems and help you determine the optimum filter maintanence schedule for your installation.
