The Multiquip RE540710 Blow-By Filter Cartridge is a genuine OEM component designed for the DCA-series super-silent diesel generator lineup, including DCA70SSJU4F, DCA150SSJU4F, and DCA180SSJU4F models. As a direct OEM replacement, the RE540710 is engineered to the exact specification required by these Isuzu-powered Tier 4 units, ensuring a correct, trouble-free installation. DHS Equipment stocks this part to keep your generator running at peak efficiency with zero compromise on air quality management. Verify your model code before ordering to confirm fitment across the DCA super-silent series.
Key Features
- Genuine OEM Filtration Media — Built to the exact porosity and capture-efficiency specification required by the Isuzu Tier 4 engine in these DCA generators, not a generic approximation.
- Drop-In Cartridge Replacement — Designed to seat directly into the existing blow-by filter housing with no rework, so service time stays short.
- Broad DCA Super-Silent Fitment — Confirmed for DCA70SSJU4F, DCA150SSJU4F (including 60Hz variants), DCA150SSJU4F2, DCA150SSJU4F3, DCA180SSJU4F, DCA180SSJU4F3, and related super-silent models.
- Crankcase Pressure Control — A correctly functioning blow-by filter maintains proper crankcase pressure, protecting oil seals and preventing contamination of the intake air stream.
- Emissions Compliance Support — On Tier 4 diesel engines, the blow-by system is part of the regulated emissions control circuit; using the OEM-specified cartridge helps maintain the engine's certified emissions performance.
A blow-by filter cartridge captures combustion gases and oil mist that escape past the piston rings into the crankcase — a normal byproduct of engine operation known as blow-by. The cartridge separates the oil content from those gases before they are recirculated back into the intake, preventing oil fouling of the intake manifold and intercooler while keeping crankcase pressure within the engine's design limits. When the cartridge becomes clogged or saturated, crankcase pressure builds, oil seals can fail, and unfiltered oil mist enters the combustion cycle, leading to increased oil consumption, smoke, and accelerated internal wear.
