Product Description
SULLAIR 2250109-321 Oil Separator Replacement is a high-performance, direct-fit oil separator cartridge designed as a reliable and cost-effective replacement for the genuine SULLAIR part 2250109-321. Engineered to meet strict OEM specifications, this separator ensures maximum oil-air separation efficiency, protecting your valuable SULLAIR screw air compressor and downstream equipment. It is the ideal maintenance solution for operators seeking optimal performance without the premium price of the original part, offering extended service life, low pressure drop, and guaranteed compatibility.


Product Advantage
1.Exceptional Filtration Performance: Achieves ultra-low residual oil content (typically ≤ 3 ppm), protecting air tools, dryers, and sensitive end-use processes from oil contamination, just like the OEM part.
2.Optimized for Energy Efficiency: Maintains a low initial pressure drop and stable differential pressure throughout its service life, reducing the compressor's energy consumption and your operating costs.
3.Extended Service Life with Robust Construction: High-strength composite end caps and reinforced media layers resist deformation under pressure pulses and thermal cycling, preventing premature failure and ensuring consistent performance for up to 8,000 hours under normal conditions.

3.Air Compressor Service & Repair Businesses: Provides distributors and independent service technicians with a high-quality, trusted alternative to offer their customers, balancing performance with profitability.
Product Operate Guide
1.Prepare the Compressor: Shut down the compressor completely. Isolate it from all power sources using Lockout/Tagout procedures. Relieve all air pressure from the system by opening drain valves. Allow the compressor to cool down.
2.Access the Separator Vessel: Locate the oil separator housing (typically a large vertical cylinder). Place an appropriate container underneath to catch any residual oil. Carefully remove the housing cover or bolts as per your compressor's manual.
3.Remove the Spent Cartridge: Extract the old oil separator cartridge. Handle it carefully as it will be saturated with oil. Inspect the housing interior for sludge or debris.
4.Critical Cleaning: Thoroughly clean the separator housing and all gasket surfaces. Ensure the oil return line orifice (the small hole in the housing base) is completely clear and unobstructed. A clogged return line is a common cause of premature separator failure.
5.Install the New 2250109-321 Replacement: Check the new cartridge for any damage. Lubricate the new O-ring or gasket with clean compressor oil. Carefully insert the new element into the housing, ensuring it seats fully and evenly on the sealing surface.
6.Reassemble: Replace the housing cover with a new seal if provided. Tighten bolts in a star pattern to the manufacturer's specified torque values to ensure an even seal.
7.Commissioning: Reset the compressor's maintenance timer if applicable. Start the compressor and observe it during initial operation. Check for any oil leaks around the separator housing. Monitor the differential pressure gauge over the next few days to establish a new baseline.
