Key Features
- OEM-Spec Output Calibration — manufactured to Husqvarna's original pressure and flow specifications, delivering consistent regulation performance that a non-spec component cannot guarantee.
- Direct Drop-In Replacement — engineered to match the original mounting points and connection interfaces on compatible machines, allowing straightforward installation by a trained technician.
- Broad Equipment Compatibility — fits the S36 dust extractor, PG830P planetary floor grinder, and HTC800RXP floor grinder, covering both dust management and surface preparation applications.
- Sustained Machine Performance — a correctly functioning regulator maintains the precise operating conditions these machines depend on; a worn or failed unit can cause erratic operation, reduced output, or accelerated wear on connected components.
- Verified Genuine OEM Part — sourced directly from Husqvarna, so the part number, design revision, and material grade match the original component fitted at the factory.
A regulator controls and maintains a set pressure or flow level within a machine's operating system, acting as the governing point between the power source and the working components downstream. When the regulator is functioning correctly, the machine operates within its designed parameters — protecting both performance output and the integrity of connected components. When a regulator degrades or fails, pressure or flow can become unstable, leading to inconsistent machine behavior, reduced effectiveness, and potential damage to other system components over time.
