Air Oil Separators

Separators are intended to be installed in the air receiver tank of rotary screw, vane style, and refrigeration compressors.

Air and Oil Separators

We can give you a complete line of high quality, efficient separators designed for the removal of petroleum or synthetic base oils in air systems and operate effectively at full pressure withstanding 50 psi differential collapse pressure.

A wide variety of filter element designs are offered including conventional or high efficiency pleated models (for requirements of below 3pm oil carryover), in vertical and horizontal mounting. Airflow capacities are available which exposed 3000 cfm.

STANDARD OIL SEPARATORS

The standard conventional air compressor oil separator is the original design for the removal of oil aerosols from the compressed air stream. This element design consists of a specific amount of a uniform grade of borosilicate glass fibers, “wrapped” onto a support tube. When properly sized to the cfm/m3/min flow rate and corresponding operating pressure of the machine, this element will provide consistent performance according to the following data:

  • Pressure drop (initial) 2-3 psi / .20 bar
  • Pressure resistance 70 psi / 5 bar
  • Efficiency 2-3 ppm / 2-3mg/m3 residual oil

PLEATED AIR OIL SEPARATOR

One common method of increasing the capacity of a given sized air-oil separator is through the use of pleated filter media. In this case, the filter media is processed through a machine whereby the normally flat surface is “pleated” or induced into a wave-like appearance. An air compressor oil separator configured in this manner can then be suited for approximately 2x the air flow capacity, as that of a standard air-oil separator, manufactured in the standard, wrapped method.

DEEP FILTER AIR OIL SEPARATOR

Another common method of obtaining increased air flow capacity from a given size air-oil separator is to manufacture the element in so called “deep filter” construction. This form of separator uses as many as three different grades of borosilicate glass, wrapped onto the support tube in larger than normal amounts. The finished product then achieves increased airflow capacity very similar to that of the pleated air oil separator, while at the same time maintaining low initial pressure drop and residual oil content. Field testing of this element has demonstrated an improvement in oil separation especially in high “challenge rate” applications, in which more oil aerosol is contained in the compressed air than is normal.

SPIN ON TYPE

This method of oil separation consists of a deep bed type oil separator element, placed inside of a pressure resistant body, or “can” similar to that of traditional oil filters. Extremely easy to replace in comparison to standard oil-separators which are enclosed in a pressurized tank, this element design is somewhat limited in application due to restrictions of air flow capacity.

VACUUM SEPARATORS

Oil separators for vacuum packages are constructed similar to that of the standard oil separators used in air compressors, and thus, will offer the same type of oil removal performance (in the range of 1-3 ppm / 1-3 mg/m3). However, such separators are designed exclusively for flow direction from the outside to the inside of the separator, and are suitable only to a maximum pressure differential (collapse point) of 22 psi / 1.5 bar.

REFRIGERATION NATURAL GAS

Special inorganic materials are required for the construction of properly functioning oil separators in refrigeration and natural gas compressor packages. In these units, gases other than air (such as Freon, ammonia or natural gas) are being com-pressed and mixed with lubricating oil which still must be removed prior to use of the gas. These types of gases, along with ancillary materials often contained in natural gas, are not suitable for typical oil separator construction, and care must be given to the proper selection of all materials in order to ensure proper functioning of the separator.
