Why Contractors Choose Genuine DutyMax EH230 Reservoir & Filter Parts

Exact-Fit Hydraulics – OEM return filters and 2-quart reservoirs are machined to Graco’s ±0.001-in tolerances, preventing the cavitation and heat that shred knock-off seals.
SmartControl 4.0 Integrity – Factory sensors read fluid pressure within ±1 PSI, sustaining perfect fan patterns shift after shift. Copycat transducers create ±8 PSI swings that telegraph as lap marks.
Warranty Peace-of-Mind – Graco’s Warranty.

Inside the Reservoir & Filtration Circuit

The DutyMax’s hydraulic loop thrives when its oil stays cool and contaminant-free. Genuine Graco parts make that happen:

Reservoir Assembly (18J579) – Powder-coated steel tank with sight-glass, 40-micron breather cap and magnetized drain plug for ferrous fines.
Return Filter (244067 30-mesh / 244068 100-mesh / 244069 200-mesh) – Easy-Out design unscrews by hand; color-coded end caps make 5-second visual checks easy.
Suction Tube (17C721) – 1-in NPT stainless elbow and crush-proof polymer hose resist collapse when pulling high-viscosity block filler.
Inlet Strainer (195840) – 60-mesh stainless basket intercepts rust flakes before they scar the Chromex™ pump rod.

Cross-Platform Compatibility Saves Truck-Stock Space

Many consumables overlap with other popular Graco rigs, letting you carry one bin for the whole fleet:

695 Graco paint sprayer – Shares RAC X tips and 60-mesh pump filters with the EH230.
Graco 230 paint sprayer – Uses the same 3/8-in NPT outlet thread, so BlueMax II hoses can swap rigs in a pinch.
Magnum Pro X7 parts – SG3 gun filters screw right into Contractor PC guns, keeping QC simple on multi-crew sites.
Graco TrueCoat 360VSP Electric TrueAirless Sprayer – FlexLiner bags double as solvent pouches for overnight pump-armor storage, cutting consumable waste.

Pro Maintenance Blueprint

Change Hydraulic Oil Every 500 Hours – Use Graco HydraMax ISO-46; cheaper AW-32 shears at operating temps, starving the hydrostatic pump.
Swap Return Filter at Oil Changes – A $22 filter beats a $350 hydro-pump reseal.
Flush at Full Pressure – Run FastFlush™ at 3 300 PSI for 45 s; low-pressure rinses leave pigment that chips tungsten seats.
Clock Your Packings – Replace UHMWPE/leather stacks every 150 000 cycles (≈750 gal). BlueLink™ pings your phone when you’re close.
Keep a Drop-In Pump – ProConnect lets you swap a complete wet-end in 60 s—cheaper than overnight freight when a rod seizes.

Frequently Asked Questions

Will an EH230 filter fit a GH 230 gas rig? Yes—hydraulic circuits are identical; just match the Easy-Out mesh to your coating.

Can I run the EH230 on a 5 kW generator? Graco recommends 6 kW continuous for full-flow spraying; a 5 kW unit limits you to 2 600 PSI.

Does the reservoir come pre-filled? No—ship-safe regulations require it to ship dry; add 1.9 L HydraMax before first start.
