Rotary screw air compressors are a type of air compressor that uses two helical screws to compress air. They are a popular choice for a variety of applications, including industrial, commercial, and automotive. Rotary screw air compressors are known for their reliability and efficiency, but they do require regular ...

There will always be a certain amount of oil carried over from a compressor. When the compressor it is running hot or is being overworked, oil carryover is made worst. The hot oil fumes then condense in the hose and in the tools. The effect can be reduced by running the compressor as cool as possible, making sure there are no leaks and that the outlet pressure regulator on the compressor is set as...

There are safety features built into every compressor we sell. These include pressure safety relief valves and thermal cut-outs. Only qualified technicians should be allowed to repair and service your compressor. Common sense prevails, including do not blow compressed air into your face.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently deve...

The volume of air delivered out of the compressor is measured per minute in liters per minute for a given pressurePiston displacement/suction capacity or any other name is based on a reciprocating piston compressor is a pure TTHEORTICAL FIGURE based on the bore, stroke, and speed of the compressor. The fad is actually what comes out of the compressor after all the inefficiencies are taken into acc...

If a compressor is turned on and running at a pressure of 10 bar. Whilst the compressor is being used the pump may not have to be on until the pressure drops to say 8 Bar. Then the compressor pump will turn on and increase the pressure till 10 bar is reached. The time the compressor is on compared to the time the compressor is turned off is the "duty cycle". So if the compressor is on as much as i...

Obviously, your business does not involve using your compressed air to spray paints, or you would know of problems a little water can cause. But water’s rap sheet is long and varied and is not limited to crimes against paint jobs. Water in your compressed air will flush away lubricants in your air tools and air powered machines, increasing wear and causing premature breakdowns. Also, it can mix...

There are some telltale symptoms of a seriously oversized rotary air compressor:• The compressor is an oily mess,• You have to buy extra oil between services,• You are having problems with your condensate drains,• You are frequently replacing downstream filters, or• You are experiencing corrosion in your compressed air system.If you suspect your rotary air compressor is oversized, ask Air Compress...

The best way to size your air compressor is to measure your actual compressed air use for at least one week of typical operations and allow for reasonable estimates of expected changes. Air Compressor Service can perform this service for a reasonable cost (free for our existing customers). Industrial air compressors are too expensive to make a mistake by buying a machine too small for your appli...

This is an excellent question because the wrong air compressor can cost you big bucks and cause untold headaches. Each type of compressor (reciprocating, rotary screw, and rotary vane are the primary types) has its own “pros and cons”, but it is not difficult to determine the most appropriate type for your application once you know a little about each one.Reciprocating, or piston, air compressors...

All compressor rooms require ventilation. Minimum room ventilation can be calculated from the formula: Qv = 1.06 N/ T for Pack unit Qv= (1.06 + 1.3) / T for Full-Feature unit Qv = required cooling air flow (m³/s) N = shaft input of compressor (kW) T = temperature increase in compressor room (usually 7°C) If the compressor is conducted, the required ventilation is the same as the fan capacity of th...

First, an internal Water Separator Drain (inside of the compressor) is NOT necessary. But it can have some benefits in two cases: 1) Screw without an integrated dryer: Using a water separator drain, we remove some water from the compressed air before it's delivered to the final area of use with less water content. 2) Screw with an integrated dryer: Using it before the dryer, some of the water gets...

Because an inverter/frequency-driven compressor is not producing more air than needed. A conventional compressor works within a pressure band. When reaching the higher pressure the machine goes into unload mode (the motor is running but no air is produced). When reaching the lower pressure again until it reaches its unload pressure again. An inverter/frequency driven compressor has less unload tim...

It has almost the same components as a conventional compressor but there is, of course, a few main differences. A frequency-driven compressor has an integrated inverter and often a more advanced control system. The inverter adjusts the motor speed to the actual air demand. This is controlled by a sensor that measures the system pressure this is signaled to the controller of the compressor. The con...

The normal payback is between 1-2 years during normal conditions and 4000 running hours per year. Not seldom do we see paybacks within a year.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

At 575 volts, a 3-phase motor draws 1 amp per horsepower. At 460 volts, a 3-phase motor draws 1.27 amps per horsepower. At 400 volts, a 3-phase motor draws 1.5 amps per horsepower. At 230 volts, a 3-phase motor draws 2.5 amps per horsepower. At 230 volts, a single-phase motor draws 5 amps per horsepower. At 115 volts, a single-phase motor draws 10 amps per horsepower. These numbers above have no s...

There is a difference in running costs between the 2 technologies. The belt-driven unit is a less expensive investment but consumes on average 3% extra energy. Also, a little bit more time has to be put into maintenance by adjusting, for example, the belt. The most suitable technology depends on the customer's needs.In order to ensure that our screw compressor operates as efficiently as possible, ...
