A cooler that is intended to use air as the cooling medium.

A dynamic compressor in which the gas is accelerated by the action of a bladed rotor and where the main flow is along the rotation axis of the rotor.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial.

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

A pressure relief valve that has its closing force provided by a spring.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

A pressure relief valve that uses a pilot valve to indirectly activate the main valve.

A physical object that is a long tube or hollow body intended for conduction of liquid, gaseous or finely divided solid materials, or used for structural purposes.

A fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A pressure relief valve that is intended to release excess pressure or admit pressure to prevent a vacuum forming when filling or emptying a pipeline or tank.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

A self operating valve that is set to open at a certain pressure level to prevent the pressure in a container or system from reaching unsafe levels.

A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.

A relief valve that is used for pressure compensation purposes by admitting (letting in) a pressure to prevent that vacuum is forming when filling or emptying a system.
