Automatic dampener

Haskel Air Driven Gas Boosters consist of a large area reciprocating air drive piston directly coupled by a connecting rod to a small area gas piston. The gas piston operates in a high-pressure gas barrel section. Each gas barrel end cap contains high-pressure inlet and outlet check valves. The air drive section includes a cycling spool and pilot valves that provide continuous reciprocating action when air is supplied to the air drive inlet.Isolation of the gas compression chambers from the air drive section is provided by three sets of dynamic seals. The intervening two chambers are vented to atmosphere. This design prevents air drive contamination from entering the gas stream.Cooling is provided by routing the cold exhausted drive air through an individual jacket surrounding the gas barrel and also through an intercooler on the interstage line (two-stage models only).Basic types of gas boosters: Key FeaturesAir driven - no electricity required No airline lubricator required Hydrocarbon free - separation between air and gas sections Pressures to 39,000 psi (2690 bar) Wide range of models Built-in-cooling on most models Standard and custom systems available Suitable for most gases Dimensions & SpecificationsAcceptable Operating TemperaturesThere are two distinct sections: the air drive section and the gas barrel section.Air Drive SectionThe ambient air condition is normally all that need be considered since this will usually determine the temperature of the air or gas drive seals and other static components. Standard air drive sections should cycle reliably within an ambient range of -4? to +65? (25?to 150?). Lower temperatures will cause excessive air/gas leakage; higher temperatures reduce seal life.Drive air directly from a compressor should ideally be warm before entering the air gas drive.Gas Barrel SectionLow temperatures normally have little effect on the operation of standard parts and seals. The heat from the compressing gas helps to balance out an acceptable temperature. Maximum average acceptable temperature 115? (240?).Gas Transfer & PressurisationHaskel are specialists in the design, manufacture, test and commissioning of standard and customised systems in a wide range of industries and applications. Our experience in high pressure gas pressurisation and transfer has enabled us to develop our reputation for high pressure gas control technology.Haskel Air or Gas Driven Gas Booster Compressors are suitable for transfer and pressurisation of: Nitrogen (N2) Helium (He) Breathing Air (N202) Nitrous Oxide (N20) Carbon Dioxide (C02) Neon (Ne) Argon (Ar) Sulphur Hexafluoride (SF6) Oxygen (02) - maximum safe working pressure 345 bar (5000 psi) Carbon Monoxide (CO)* Hydrogen (H2)* Methane (CH4)* Ethylene (C2H4)* Deuterium (D2)* Natural Gas (CH4) - often contains a high proportion of C02 & N2 * *For these gases (10 - 15), the gas booster must be operated in a safe and well-ventilated area and vent(s) piped to controlled environment.Liquefied type gases (propane, C02, nitrous oxide, halons, etc.) can be boosted as a liquid or gas in controlled applications. Consult your Haskel Asia representative or the factory for precise recommendations.Haskel boosters are noted for their cleanliness and can handle pure gases such as oxygen without risk of any contamination. (Special cleaning required. Please consult your Haskel Asia representative.)
