Air Preparation Unit

The Festo LFR-3/4-D-MAXI is a filter regulator designed to clean and control compressed air in pneumatic systems. It combines particle filtration with precise pressure regulation in a single housing. The unit is supplied new as part number 159632 and carries the Series D designation. It is intended for technicians and engineers maintaining industrial air supply lines.

Suited for Contaminant Removal

This device suits workshops that need to remove solid particles and water condensate while maintaining a stable downstream pressure. It is not intended for applications requiring oil-free air to a higher purity class, nor for systems where a separate lubricator is required downstream. Buyers needing integrated lubrication or finer coalescing filtration should look at alternative configurations.

Series D Platform

The critical specification is the Series D platform identifier, which defines the internal component geometry and seal materials. Verifying this series code against existing manifold assemblies or spare-parts inventories confirms whether the regulator will integrate without modification. The part number 159632 provides the exact ordering reference for this series.

Questions about this item

What port size does the LFR-3/4-D-MAXI filter regulator use for piping connections?

The unit has a G 3/4 thread on both inlet and outlet ports for direct pipe mounting.

Which step is most often missed when installing the 159632 filter regulator?

Installers frequently forget to fit the mounting bracket before tightening the pipe connections, making alignment difficult afterwards.

When should the filter element inside the LFR-3/4-D-MAXI be replaced?

Replace the element when the pressure drop across the bowl reaches the red zone on the integrated indicator or after the interval set in your maintenance schedule.
