Why Desiccant Filters Are Essential

A desiccant filter is a vital defense against moisture and airborne contaminants in hydraulic systems and gearboxes. When air enters a reservoir or gearbox, it often carries water vapor and fine particles that can compromise system performance. During temperature fluctuations, this moisture condenses into water, leading to oxidation, corrosion, and premature equipment failure.

Protection Beyond Standard Breathers

Replacing a standard breather cap with a desiccant breather filter provides advanced protection by trapping moisture and microscopic particulates before they enter your system. This keeps fluid clean, improves reliability, and extends equipment life.

Industries that depend on moisture control and contamination prevention - such as manufacturing, marine, and heavy hydraulics - rely on Techknow Engineering Enterprise for high-performance desiccant filtration solutions that minimize downtime and reduce maintenance costs.

How Desiccant Filters Work

Desiccant filters combine air filtration and moisture absorption in one lightweight breather unit. As air enters, it passes through a fine 2-micron absolute-rated filter, removing solid particulates. Simultaneously, the drying agent absorbs moisture to protect the hydraulic fluid. The drying agent changes color (orange to dark green, or blue to pink) as it becomes saturated, making it easy to identify when replacement is needed - ensuring reservoir cleanliness at all times.

Advanced Protection for Your Hydraulic Systems

Built with a durable polycarbonate casing, impact-resistant standpipe, and advanced check-valve technology, our inline desiccant filters offer long-lasting protection against both moisture and particulate contamination. These filters are ideal for industrial and mobile applications, helping equipment run smoothly and reducing costly downtime.

FAQ

Desiccant filters protect hydraulic reservoirs, gearboxes, storage tanks, and other equipment by removing airborne moisture and fine particles. They ensure only clean, dry air enters the system, preventing oxidation, corrosion, and fluid degradation.

Incoming atmospheric air passes through a 2-micron filter element and moisture-absorbing silica gel. The silica gel changes color when saturated, providing a visual indicator of when replacement is required.

Our desiccant filters reduce fluid oxidation, corrosion, and system downtime by preventing moisture and dust from entering hydraulic oils, gearboxes, and storage tanks. This extends fluid life and ensures reliable performance.

They can replace standard dust or breather caps in environments prone to humidity or dust. Typical installations include hydraulic reservoirs, gearboxes, storage tanks, and other sealed equipment exposed to airborne contaminants.

  • 2 µm particle filtration
  • Airflow capacity up to 5,000 l/min
  • Durable polycarbonate housings
  • Dual check-valve options available
  • Visual or electrical saturation indicators on selected models

Replace desiccant filters when the silica gel changes color (orange to dark green, or blue to pink) or according to the recommended maintenance interval of your specific application.

Yes. We supply rebuildable models where only the silica gel beads and breather element are replaced, making them a cost-effective and sustainable option compared to full unit replacement.
