Description
Accu-Zorb AZ15 – Oil/Water Separator for Compressed Air Condensate Treatment
The Accu-Zorb AZ15 from Air System Products Inc. is a compact, high-performance oil/water separator engineered to treat condensate from compressed-air systems using soluble or emulsifying lubricants. Ideal for small to mid-size air compressors, the AZ15 uses a proven multi-stage separation process combining sediment filtration, pre-absorption, and zeolite media polishing to remove oil contamination and produce clean, environmentally compliant discharge water.
Key Features:
- Optimized for polyglycol, ATF, and detergent-based lubricants
- Zeolite filtration media captures and retains emulsified oil for cleaner discharge
- Translucent oil collection container allows quick visual level inspection
- Sample valve and flow indicator simplify performance checks and maintenance
- Optional remote flow indicator, equalizer manifold, and heater kit available for demanding environments
Applications:
- Rotary screw and vane air compressors up to the AZ15 capacity range
- Manufacturing, automotive, and service facilities handling emulsified condensate
- Any installation requiring EPA-compliant condensate discharge
The Accu-Zorb AZ15 Oil/Water Separator delivers reliable condensate management while reducing waste hauling costs by up to 98%. Designed and built in the USA by Air System Products, Inc., it provides long-term durability, low maintenance, and dependable protection for your compressed-air investment.
Frequently Asked Questions
Accu-Zorb Oil/Water Separator
▶️ Question: Where should I install the Accu-Zorb, and do I need a floor drain?
Answer: Install the Accu-Zorb on a level surface with enough clearance to remove and replace filters. It should be located near a sanitary floor drain so the treated water can discharge by gravity—pumps are not recommended. Proper leveling ensures effective oil separation and prevents overflow issues.
▶️ Question: Do I need to prepare the filters before startup?
Answer: Yes. Remove the Pre-Absorber and Media Bed(s) from their packaging and hose them thoroughly until the rinse water runs clear. This step removes dust and trapped air pockets that could otherwise restrict flow or reduce adsorption efficiency.
▶️ Question: How do I adjust the oil skimming height and monitor oil collection?
Answer: Once the unit is filled with clean water, lower the Oil Outlet Tube until its orifice is about ½–¾ inch above the water level. Over time, separated oil will accumulate in the translucent container. It can take weeks or months before visible oil appears, depending on the amount of condensate produced.
▶️ Question: How often should I check or replace the media?
Answer: Every two weeks, draw a water sample from the Sample Valve and compare it to clean tap water. If the sample appears cloudy, replace the Pre-Absorber and Media Bed(s). Keeping a log of test results and service intervals ensures consistent performance.
▶️ Question: Why is there water collecting in the oil container?
Answer: This usually indicates that the separator is not level or that the Oil Outlet Tube is set too low. Heavy condensate surges can also cause temporary water carry-over. Re-level the unit, slightly raise the tube, and consider adding an Equalizer if surges are frequent.
▶️ Question: What types of compressor lubricants are compatible with the Accu-Zorb?
Answer: Accu-Zorb is designed for soluble and emulsifying lubricants such as synthetic blends, polyglycols, and detergent motor oils. Insoluble mineral or PAO oils separate more easily and may be better suited for Accu-Sep models. When uncertain, perform a simple “jar test” to see how well the oil separates from water.
▶️ Question: Are accessories available for cold or remote installations?
Answer: Yes. Optional accessories include heaters for freeze protection, a Level Minder that signals when the oil container is full, a Remote Flow Indicator to show restricted flow, and an Equalizer kit to balance multiple separators during high condensate flow conditions.
