Genuine OEM EL-AV EL+ Series 4000-hour service maintenance kit sized for the ELBD20INV rotary screw compressor (20 HP). Pre-bundled by HP rating so there's no part-number lookup at service time — the kit contains everything needed for a complete 4000-hour scheduled service per the EL-AV maintenance schedule.

What's in the 4000-Hour Kit

• Air inlet filter cartridge
• Spin-on oil filter
• Oil / air separator element (complete change)
• Lubricant charge sized for the airend (top-up; pair with 8000H Synthetic Oil pail for full change)
• Sealing washers, O-rings, and gaskets for filter and separator housings
• Service-interval consumables per the EL-AV extended-service checklist

Service interval: Every 4,000 operating hours per EL-AV recommended maintenance schedule. Includes everything in the 2000-Hour kit plus the separator change.

Why Use OEM Kits

• Preserves warranty coverage — non-OEM consumables can void EL-AV factory warranty
• Exact-match tolerances on the airend separator critical for oil-carryover specs
• Pre-bundled per HP class — eliminates the risk of ordering the wrong micron rating or seal kit
