No handling fees

When you shop online for products and you finally find a site that have good prices. You proceed and order the product and just before payment you see that an additional 65 Euro handling fee was added (in addition to the shipment cost). I just hate this kind of experience !

MH Oxygen Products

 We keep our most popular products in stock, ready to ship.

We focus on EDS oxygen systems, the newest and best technology making the oxygen last longer and you flying further. These systems use a electronically controlled pulse demand system. This technology, contained in the O2D2 and O2D1 units, takes into account your altitude, and breathing to provide the perfect quantity of air just when you need it. These units can be set on the fly to provide oxygen at certain altitude or can be activated manually with varying degrees of oxygen output if needed. Whichever setting the unit is set to, it will only provided oxygen when the wearer breaths in, conserving oxygen, making the cylinder last longer.

This table shows the clear advantage of using an EDS system over a normal constant flow system

Two types of EDS kit are available O2D1 and O2D2, single and dual person kits for single and tandem occupant operations. For single person used we recommend the O2D1 with the AL180 cylinder. For 2 person operation, we suggest the O2D2 with an AL415 cylinder as long as this will fit comfortable in your aircraft. Of course other sizes are available. All our kits come with everything you need to fly and more, like various cannulars and face masks, all tubing and a carry case for the kit.

Have your own cylinder?

If you already have your own cylinder or want to use a different kind of bottle, you will want to look at our XCR regulator kits. These are very similar to the above kits but are designed to fit on existing cylinders. Everything you need is included in the kit including a gauged XCR regulator so you can always see how full your cylinder is. 


We also have various accessories for your oxygen systems. Very useful are the extra or spare cannulars perfect to keep as replacements or to swap out so each person ca have their own, perfect for club glider use for exemple.
