In-Line and Off-Line

Schroeder’s In-Line and Off-Line filtration products provide many choices to allow for portable cart mounted and plate mounted kidney loop systems, air operated and variable flow systems are also available that allow for greater flexibility and the ability to filter higher viscosity fluids.

Single Pass Filter Kits (2K9 & 3K9)

The 2K9 includes two patent-pending K9 filters supplied in series as a single filter assembly providing in-line single pass particulate and water filtration.

The 3K9 includes three patent-pending K9 filters supplied in series as a single filter assembly providing in-line single pass particulate and water filtration.

Both the 2K9 and the 3K9 kits accept HF4 spec elements. The 900 psi rating covers almost all transfer line pressure specs including air driven transfer systems.

Mobile Filtration Systems

Schroeder’s new generation of portable filtration carts offer many new features to the user. The Schroeder Mobile Filtration System is a compact, self-contained filtration system equipped with high efficiency, high capacity elements capable of removing particulate contamination and/or water quickly, conveniently and economically. It is perfect for cleaning up existing systems as well as for pre-filtering new fluids, since new fluids often have contamination levels significantly higher than that recommended for most hydraulic systems.

The MFS single filtration unit can remove either water or particulate contamination.

The MFD dual filtration unit can be used to remove both water and particulate contamination, or for staged particulate contaminant removal.

Air-Operated Mobile Filtration Systems

Schroeder Industries now offers a mobile filtration system with a pneumatic motor in place of the standard electric motor. The pneumatic motor offers the same flow capability using the same components, but without the need for an electrical outlet. This provides a major advantage in the application of this unit. With no need for an electrical outlet, it is more portable than the standard electric-motored skids and carts. Because most trucks and industrial machinery are already equipped with an air compressor, a simple connection to the 1/4” NPT port will easily power the 1.5 HP (or 4.0 HP) motor. At 70 psi, and 2000 rpm, this motor consumes less than 40 cfm (70 cfm for the 4.0HP motor) of compressed air. Because no electricity is used, the pneumatic motor is ideal for working in hazardous environments such as mines.

Kidney Loop System

Schroeder’s off-line Kidney Loop System is a stationary version of the Mobile Filtration System. It is a compact, self-contained filtration system equipped with high efficiency, high capacity elements capable of removing particulate contamination and/or water quickly, conveniently and economically. This off-line system can be used to supplement in-line filters when adequate turnover cannot be achieved in the system. It is also ideal for water removal. Its modular base eliminates hoses and fittings between components.

The KLS single filtration unit can remove either water or particulate contamination.

The KLD dual filtration unit can be used to remove both water and particulate contamination, or for staged particulate contaminant removal.

Auto Flush Filter Cart

The Auto Flush Filter Cart is designed to transfer fluid through (2) K-size filters in series for staged particulate or water/particulate removal. Both filters are top-loading and include element indicators in the cap. A 40 micron strainer filter protected laser particle monitor samples from the pump discharge and displays ISO contamination codes on the control panel. The monitor allows user to input a desired cleanliness code. An optional water sensor with relay output is available with set point entered by user.

X Series Filter Skids

Schroeder’s X Series filtration skids are compact, self-contained filtration systems equipped with high efficiency, high capacity elements capable of removing particulate contamination and/or water quickly and economically. They supplement in-line filters whenever the existing filtration is incapable of obtaining the desired ISO cleanliness level. Standard X Series skids include a hydraulic pump, electric motor, and either a single or dual K9 or QF15 housing. Many different component combinations provide the flexibility to match specific system viscosity, flow, and cleanliness requirements. Multiple housing lengths give the option of adding additional dirt holding capacity.

It is not uncommon for viscosity to be overlooked when specifying an off-line filtration unit. The results of this oversight can severely affect system efficiency and longevity, and render the filtration system useless when high viscosity fluid causes the filter to be in constant bypass. Schroeder X series carts take the viscosity into consideration with their part numbering system so that viscosity is addressed at the onset.
