Features
SS-263 Product Features
- Smart Speed Control: Delivers high air flow for fast response to big signal changes, then automatically switches to low flow for precise small adjustments.
- Higher Flow Capacity: Provides about three times the flow of the 2625 booster, so you need fewer parts and simpler piping.
- Quieter Operation: Special exhaust passages reduce noise for a better work environment.
- Easy Tuning: Built-in bypass restrictor lets you adjust performance on-site for any signal range.
- Ready Air Connections: Two 1/4 NPT ports on both sides make it simple to add a Fisher 377 trip valve or other accessories.
- 3-in-1 Port: One connection does triple duty-1/4 NPT for diagnostics, 1/4 NPT for handwheel bypass, or 3/4 NPT for standard use.
- Tight Shutoff: Soft-seated valves prevent air leaks and ensure fail-safe operation if plant air goes down.
- Rugged & Compact: Flanged mounting means less vibration, simpler tubing, and easier maintenance in a smaller package.

FAQ
Why Engineers Prefer Fisher SS-263
Q: How is SS-263 different from standard boosters?
A: Standard boosters just amplify air flow. SS-263 adapts-delivering high speed for large signal changes and precise control for small adjustments. It's built for digital valve systems, not just general pneumatics.
Q: What operational issues does it fix?
A: Three main ones:
Speed vs. stability trade-off - Get both, not one at the expense of the other
Air waste - Tighter sealing cuts unnecessary consumption
Component wear - Smoother response extends equipment life
Q: Real-world payoff?
A: Lower utility costs, fewer maintenance calls, and better process control. For critical applications, it eliminates the compromise most boosters force on you.
Q: Who should consider it?
A: Anyone running digital valves where response time and control precision both matter. It's become the standard solution for applications that can't tolerate overshoot or instability.
