Advanced Deaerating Filtration with Air Fusion Technology


Meet the ultimate solution for air-removal filtration. Schroeder Industries Air Fusion Technology (AFT) is an in-tank hydraulic filtration system designed to remove entrained air, reduce fluid turbidity, and improve reservoir performance.



What are the risks of air contamination in hydraulic systems?


Air contamination is a common, destructive intruder in hydraulic equipment across virtually every application. Without effective air removal filtration, your equipment (and budget) are vulnerable to the following:


  • Accelerated Oil Aging: Oxidation occurs when oxygen chemically reacts with hydraulic fluid. This speeds up the process of oil aging, and contributes to harmful byproducts.
  • Varnish / Gel-Like Buildup: Oil degradation produces sticky, gel-like contaminants known as varnish. Varnish deposits on hydraulic valves and other components can cause the components to stick, or even become fully jammed.
  • Cavitation: When air enters the hydraulic circuit, cavitation can occur. As air bubbles coalesce and violently collapse under high pressure, they can cause shock-waves/damage to pumps and other components.
  • Microdieseling: A similar phenomenon to cavitation. Air bubbles can combust under high enough pressure, causing thermal oil damage and accelerated aging.
  • ‘Spongy’ Hydraulics: Unlike fluid, air is compressible, so high quantities of air in the hydraulic system can cause delayed responses in the machine’s actions.

Why Choose Air Fusion Technology (AFT) Filtration?


An air removal in-tank filter is one of the best defenses against air entering the hydraulic circuit. When put to the test against a conventional in-tank filter, Schroeder Industries’ AFT reduced the amount of air which entered the suction line on the first pass by 20%.



 
 

What makes Air Fusion Technology so effective?


Every inch of the AFT filter is engineered for optimal air removal and filtration performance:

The unique filter head design swivels independently of the inlet port, allowing tool-less element change-outs. Fixed head options are available.

A specialized bypass valve in the head of the filter allows the filter to de-aerate fluid even when in bypass for greater filtration efficiency.

The patented end-cap design allows bypass flow to enter the top of the element while still being subjected to the diffuser shroud. This helps maximize filtration.

Schroeder’s patented Lock & Key™ Quality Protection element design ensures only high-quality, approved elements are being used. To ensure that the AFT performs at its full potential, it’s important to use only high-quality filter elements.

The de-aeration diffuser shroud significantly reduces fluid turbidity. Less turbulent fluid allows for faster bubble coalescence and improved air filtration

The internal flow distribution cone redirects fluid towards the top of the reservoir, allowing air to exit the hydraulic fluid more easily.

How can Air Fusion Technology help with reservoir downsizing?


Tank Optimization is the process through which Schroeder Industries identifies and resolves design flaws in hydraulic reservoirs, thus improving tank performance.

One of the key roles of a hydraulic tank is air removal. In order to decrease fluid velocity and allow time for air to coalesce and escape the oil, reservoirs are often made larger than needed for their application.

However, an over-sized reservoir is not an ideal solution, as it requires overall higher oil and material costs, adds weight to the system, and limits design capabilities.

Air Fusion Technology Schroeder Industries’ secret weapon for optimizing tanks.

Because the AFT is so effective at air removal, the reservoir does not need to be over-sized in order to allow air dissipation.

By implementing an AFT, customers have seen tank size reductions up to 60%!
