SINFT® Respirator Special Filter Elements
Desiccant Breather Replacement — Full-Range Cross-Reference
SINFT® designs, manufactures and markets a complete line of OEM-compatible respirator special filter elements — desiccant breathers. All SINFT replacement breathers feature high-efficiency particle filtration combined with moisture-absorbing desiccant media, providing "will fit" and "will function" interchangeability with original Des-Case, Hydac, Leemin, RMF, and ETON products.
Our SINFT respirator special filter program covers all major series: DC / VG / EX / HG for Des-Case; BD / BDE / BDH / BDF for Hydac; DAB for Leemin; ACL / ACM for RMF; BFD for ETON — plus the full range of tank breathers and accessories.

Keeps oil clean and dry, preventing oxidation and component wear
Reduces maintenance | Extends oil life“Every time a tank breathes, unfiltered air introduces moisture and particles that damage oil and components. SINFT breathers stop this problem at the source.”
What Sets SINFT Apart · Quality You Can See
Advanced engineering meets rigorous testing — SINFT desiccant breathers outperform competitors in moisture absorption, structural stability, and indicator sensitivity.
| Feature | Description |
|---|---|
| Domed Cap Design | Better water runoff and corrosion resistance — prevents moisture pooling on top. |
| Integrated Nylon Standpipe | Excellent vibration resistance and even airflow distribution throughout the filter media. |
| High-Capacity Check Valves (VG / EX Series) | Prevent moisture backflow when system is idle, significantly extending breather service life. |
| Polyester Filter Element (3μm) | Effectively removes airborne contamination before it enters the reservoir — β≥200 absolute. |
| Honeycomb Oil Mist Reducer (EX Series) | Reduces oil mist contamination and returns oil to the tank, keeping the work environment clean. |
| Silica Gel with Color Indicator | Blue-to-pink color change provides visual saturation check — easy to know when replacement is needed. |
| CE & MD Directive Certified | Compliance with EU safety standards — certified reliability for global industrial applications. |
Select Premium Desiccant Material
SINFT sources only high-quality silica gel materials, each type selected for specific application requirements. Three silica gel options are available to match original desiccant specifications:
- Blue Silica Gel: Color changes blue → pink on saturation — standard indicator type, commonly used in DC / VG / Leemin cross-reference models
- Yellow Silica Gel: Color changes yellow → green — high-sensitivity indicator type, designed for Air Sentry / Hydac replacement models
- Mixed-Color Silica Gel: No color-change indicator, durable type — used in RMF / ETON replacement part numbers for extended service life
All filter media and raw materials undergo strict incoming inspection and performance verification — ensuring consistent adsorption capacity and long-term filtration reliability.
