We deliver high-pressure compressors and the complementary modules for purification, storage and filling.

High performance complete solutions for reliable compression, purification, storage and recovery of inert gases such as helium and argon. This compressor series provides economic efficiency to the maximum due to loss-free compression by means of returning condensation and leak gases.

Take profit of our many years of experience in planning and construction of special systems for applications such as helium recovery, filling plants and different test plants as well as various other helium applications.

Inlet pressureatmospheric150 bar (2100 psi)
Delivery capacity6 m3/h (3,5 cfm)700 m3/h (420 cfm)
Final pressure10 bar (140 psi)420 bar (6100 psi)

We individually calculate compressor and drive power according to your application requirement. In this way, we perform the best possible efficiency and highest economic feasibility for you.

The Right Compressor for a Lagoon 42 Catamaran


I am purchasing a Lagoon 42 Catamaran and want to install a Scuba compressor.  I have a FISCHER PANDA FP Marine Genset AC – PMS08 Mini-DP 120V already installed on the boat.    

The boat will be delivered to CT and then in November, I plan to sail it down to the Caribbean. I was wondering if you guys can help with this project, or at least advise on which compressor to purchase and where to install and best design for the system.  


YachtPro™ Essential (YP100)

Our Yachtpro™ Essential (YP100SF-D) compressor system is preferred by motor cat and sail cat owners everywhere. Here is a downloadable page with details, features, specifications and drawings to give you some reference. 

The YP100 is completely automated. You only need to connect your tanks, open the valves and turn the system on. You are then free to attend to other duties while your tanks fill to the programmed pressure. The compressor automatically stops when your tanks are full. 

The system comes with a Variable Frequency Drive (VFD) to alleviate the tremendous inrush draw typically experienced when starting an electric motor. You can use the Yacht Pro Essential on much smaller generator sets than other compressors of this size; very important for boaters. 

The entire compressor system is pre-mounted on a base of King Starboard to make installation as easy as possible. Just place on a suitable surface. screw the base panel down, hang the VFD control box, hook up your electric service – and you are ready to go!

We supply everything you need to install and run your compressor system. 

NOTE: At this time, the standard configuration of the YP100 is compatible with 200-240v, 50/60Hz 1ph or 3ph electric service. Higher voltage configurations are available for an additional charge. 

Things to consider:

  • Does your generator have a 230v outlet you can utilize for the compressor?
  • How many divers will the system need to support? Making how many dives per day?

We can modify the compressor output to best fit your boat plans. I’ve attached a page illustrating just a few of the options we use on a regular basis. Let us know if you have a particular need or design requirement. We are happy to help. 

L&W Compressors at DEMA 2017

DEMA 2017 Was a Great Success

Last week, LW Americas set out to Orlando, Florida for the annual DEMA Show, the largest trade-only event in the world for companies doing business in the scuba diving, ocean water sports and adventure/dive. The booth was steadily visited throughout the show and we heard from multiple people that our booth seemed to be the busiest compressor booth at the show.
