Multiquip H216169 DEF Tank Vent Filter

The Multiquip H216169 is a genuine OEM DEF Tank Vent Filter designed for the DCA series ultra-silent and super-silent diesel generators, including DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F variants. As a direct Multiquip OEM part, H216169 is manufactured to the exact specifications required by these Tier 4 Final compliant generator platforms. Sourcing the correct vent filter matters — DEF system integrity depends on a properly functioning filter to prevent contamination and maintain emissions compliance. DHS Equipment stocks this part to keep your DCA series generator operating within spec.

Key Features

• Genuine OEM Filtration Media — Manufactured to Multiquip's exact porosity and chemical-resistance specifications, ensuring DEF fluid purity is maintained throughout the venting cycle.
• Direct-Fit Replacement — Engineered to seat correctly in the DEF tank vent port on DCA series generators without modification, making installation straightforward during scheduled service.
• Broad DCA Series Compatibility — Fits DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, DCA300SSJU4F, and their corresponding variant models across both 50Hz and 60Hz configurations.
• Protects SCR Emissions System — A clean, unobstructed DEF tank vent prevents pressure buildup and keeps contaminants out of the selective catalytic reduction system, protecting injectors and dosing components from premature wear.
• Emissions Compliance Support — Tier 4 Final generators require uncompromised DEF system performance; using the correct OEM vent filter helps maintain the emissions integrity these machines are certified to meet.

The DEF tank vent filter allows the diesel exhaust fluid tank to breathe as fluid is consumed and the tank volume changes, preventing vacuum lock or pressure buildup that could restrict DEF flow to the dosing system. A clogged or degraded vent filter can cause DEF delivery faults, trigger fault codes, and ultimately derate or shut down the generator to protect the aftertreatment system. Replacing this filter on schedule is a low-cost step that protects the far more expensive SCR components downstream.
