Discover the best coltri compressor for every application

In the world of diving, there are various types of compressors used to supply air to divers. These compressors take in air and compress it to suitable pressures for diving. Below, I will mention some of the most common compressors used in diving: 

High-pressure compressors: These compressors are designed to compress air at pressures higher than those used in standard recreational diving. They are used in technical diving and commercial activities that require specific breathing gases. High-pressure compressors can compress air at pressures higher than 4351 Psi. Some can even reach pressures of up to 14503,8 psi or more, depending on the specific application. Coltri offers a wide range of compressors of this type.

 -  Portable Line: These are the most commonly used compressors in the world. Portable air mini-compressors even on board. Lightweight and practical, these compressors have made history in the Coltri world, boasting excellent portability to accompany you everywhere. You can find them in electric and gasoline versions. 

 -  Efficient Line: This is one of the favorites among professionals. They are silent and high-performance compressors. They have an impressive capacity (from 100 to 315 liters per minute).

 -  Prime Line: The compressors in the Prime line are high-pressure air compressors with condensate separator and dryer (optional feature in the Super Silent TPS model) for tropical climates.

 -  Heavy-Duty Line: This is the highest performing line. Very powerful and tireless, they minimize the recharge time. 


Low-pressure compressors: These are specially designed equipment to provide air to divers and underwater workers performing tasks in underwater constructions, such as building or repairing structures, pipes, or oil platforms. Unlike compressors used in recreational diving, where air is supplied at moderate pressures (generally around 2900-4351 bars), low-pressure compressors generate air at much lower pressures, usually between 101 and 174 psi. These lower pressures are sufficient to provide a constant supply of air to underwater workers while they perform their tasks. Coltri offers the Tankless line for professionals. 

NITROX Membranes 

They are also known as oxygen enrichment membranes. These devices used in diving provide a breathable gas mixture with a higher oxygen content than normal atmospheric air. These membranes have several important features in diving: 

1. Oxygen enrichment: The main feature of NITROX membranes is their ability to enrich the oxygen content in the breathable gas mixture. Normally, atmospheric air has around 21% oxygen, but NITROX membranes can increase this percentage according to the diver's needs. 

2. Safety and mixture control: These membranes allow for greater control and safety in the gas mixture used for breathing during diving. By adjusting the membrane settings, a specific mixture with a desired oxygen percentage can be achieved, thus avoiding risks associated with inappropriate mixtures. 

3. Nitrogen removal: In addition to oxygen enrichment, NITROX membranes can also remove some of the nitrogen present in the air. This is beneficial for divers who want to reduce nitrogen exposure, which can help prevent decompression sickness. 

4. Portability: NITROX membranes are compact and portable devices, making them suitable for use in different diving environments. They can be easily transported on boats, used for shore diving, or even utilized on diving expeditions in remote locations.
