Conventional Wrap Style
The standard conventional 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

KELTEC utilizes special inorganic materials for the construction and proper function of oil separators for refrigeration and natural gas compressor packages. These units have other gases being compressed and mixed with lubricating oil which 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. KELTEC takes great care in the proper selection of all materials in order to ensure proper functioning of our separators.

KELTEC Technolab has the longest history of successful oil separation technology for this field. From the coalescing materials, to the sealing methods used, you can be confident in our refrigeration and natural gas oil separators.

Ultimate in Compressed Air Filtration
The Compressed Air Contamination Issue
Atmospheric air entering the air compressor is the single biggest contributor of contaminants into a compressed air system, that over time, reduce the efficiency and life span of oil filters and air-oil separators. Keltec-Technolab has a wide range of air intake filters, utilizing cellulose, synthetic and fiberglass medias, of varying efficiencies, that will greatly reduce this contaminant and provide for longer system life.

Like all of our products, KELTEC Technolab oil filters are built of the highest quality materials and workmanship.
Specific filtration levels are obtained through the exclusive use of high-grade filter media and consistent surface area control, obtained by a strict maintenance of pleat quantity and depth. Leakages are prevented by the positive seals obtained with both plastisol and epoxy encapsulation. Viton seals are used where applications of synthetic oil are typical

In the compressor system, the oil itself must be filtered on a regular cycle to remove contaminants that may enter the compressor and damage the unit. This is accomplished through the installation of a lube oil filter, either in cartridge, or spin-on form, which then ensures that all of the oil is cleaned as it moves through the filter.

Filtering in 5–25 micron range (depending upon application), it is again, the depositing of oil-borne contaminants over time, that causes the oil filter to continually increase in differential pressure to a point at which it must be replaced in order to continue proper filtration of the compressor oil.

The Correct Compressor Lubricant is Crucial for Operational Success
KELTEC Technolab offers a full range of PAO, diester and polyglycol based compressor lubricant, designed to match the most difficult compressor application. Continual testing and research combines to ensure that the most effective oil additives are used in order to virtually eliminate such common problems such as foaming, oxidation, and deposit formation.

KELTEC Technolab’s coalescing filters provide the highest level of clean, compressed air with a minimum loss of energy.

KELTEC Refrigerated Dryers actively remove condensate to achieve extremely dry compressed air.
The importance of compressed air as a provider of energy for the modern industrial process is widely known. What is often overlooked, however, is the need to provide quality treatment for this air.

Air entering the system contains condensate which, when cooled, will turn into liquid water, causing extensive damage, not only to the compressed air network, but also to the finished product.

KELTEC Dryers actively remove condensate to achieve extremely dry compressed air allowing for less system downtime, reduced cost on maintenance and filtering installation, and improved finished product.

The Chicopee separator design utilizes a unique media configuration and innovative structural integrity components to achieve exceptionally efficient oil removal.

KELTEC Technolab offers high quality Activated Aluminum Desiccant for the absorption of water vapor and other gases from compressed air.
KELTEC Technolab Activated Alumina Desiccant is highly porous with a large surface area that will not weaken or break when subjected to high liquid concentrations. Our high crush strength and strong durable shipping bags allow for easy transport.

The unique centrifugal action in our water separators helps KELTEC Technolab protect your equipment investments.
KELTEC-Technolab water separators have been designed for the removal of bulk liquid water and a significant portion of particulate from compressed air and gases. Unique centrifugal action removed contaminants at low-pressure drop for maximum energy savings.

Note: While highly efficient, condensate separators will not remove 100% of the water from the air stream. Additional coalescing and particulate filters downstream are typically required to remove the fine traces of oil, water and particles.

High-efficiency ASHRAE filter for HVAC applications
Hydrophobic glass fiber “mini-pleat” design in “V–bank” configuration for the maximum amount of filter media, providing for superior dust-holding capacity with exceptionally low pressure drop.

Pleat spacing and uniformity is assured with physical division of each individual pleat, assuring equal and smooth airflow through the filter media.
