How SPC's catalog is organized by what the air is doing.

30 categories organized by what compressed air or pneumatic motion is doing for the customer. Pick the system, then the layer, then the category — the catalog is shaped like the conversation.

Compressed Air System →

Generation, treatment, storage, control, distribution, end-use, monitoring, and service — the plant air system, end to end.

Generation Treatment Storage Control End-Use Monitoring Service & MRO
Generation

Compressors

The heart of the system — six compressor types, one duty-cycle decision.

6 product types
Treatment

Air Dryers

The core of air treatment — five dryer types, one dew-point decision.

5 product types
Treatment

Air Treatment

First stage of treatment — drop the bulk water before it ever reaches the dryer.

2 product types
Treatment

Condensate Management

Three products that handle what the aftercooler and dryer pull out — legally.

3 product types
Treatment

Filtration

Six filter types, one train — solids, liquid oil, vapor, dust, and the medical polish.

6 product types
Storage

Air Receivers

The system's buffer — four tank types, one sizing rule, one code stamp.

4 product types
Control

Compressor Internal Valves

The three valves inside the rotary-screw — capacity, oil-temperature, and cold-start control.

6 product types
Control

System Safety Valves

Two valves the law writes the spec for — backflow protection at the compressor, ASME relief on every vessel.

2 product types
End-Use

Nitrogen Generation

Three formats of on-site nitrogen — from one PSA core, sized to the application.

3 product types
Monitoring

System Monitoring

Five instruments, one rule — what you can't measure, you can't manage.

6 product types
Service & MRO

Service & MRO

The recurring kit — oils, filter elements, belts, and drains that keep an installed system running, on one quote.

14 product types
Service & MRO

Service Parts

The line that recurs every quarter — oils, filters, valves, and the OEM cross that wins the PO.

System 2 of 2

Pneumatic Automation System

Machine-level air prep, distribution, control, actuation, and exhaust — the layer where compressed air becomes motion at the point of use.

Air Preparation Distribution & Conveyance Control & Valving Actuation Motion Control Sensing & Feedback
Air Preparation

FRL Units

The machine-inlet conditioning step — seven product types, one air-prep decision per drop.

8 product types
Distribution & Conveyance

Functional Fittings

Push-to-connect bodies that do a second job at the port — isolate, check, throttle, swivel, vent. The Sang-A PTC functional-fitting line.

6 product types
Distribution & Conveyance

Modular Piping

The plant header — extruded aluminum mains, push or clamp joints, no thread, no weld, no rust.

1 product types
Distribution & Conveyance

Push-to-Connect Fittings

Five push-to-connect tiers, graded by body material and certification — the Sang-A flagship core.

5 product types
Distribution & Conveyance

Quick Couplers

Tool changeover at the hose end — industrial socket, safety-vented socket, and the profile-matched plug.

3 product types
Distribution & Conveyance

Specialty Fittings

Instrumentation double-ferrule and DOT air-brake — regulatory connection families, not push-to-connect.

2 product types
Distribution & Conveyance

Threaded Pipe Fittings

Black and galvanized NPT fittings — the elbows, tees, couplings, and nipples that build and repair iron-pipe air mains.

2 product types
Distribution & Conveyance

Tubing

Four flexible tubing materials — PE, PU, nylon, FEP/PTFE — matched to chemistry, pressure, and motion.

4 product types
Control & Valving

Directional Control Valves

The electrical-to-pneumatic translation — a PLC output energizes a coil, a coil shifts a spool, the spool drives the cylinder.

5 product types
Control & Valving

Manual & Shutoff Valves

Hand-operated and lockable isolation — turn a branch on, turn it off, lock it out for service.

3 product types
Control & Valving

Silencers

One silencer per valve exhaust port — count the valves, quote the set, own the reorder.

2 product types
Control & Valving

Valve Terminals & Regulators

The IIoT pivot — smart valve terminals that collapse the wiring and stream diagnostics, plus electronic pressure regulation.

2 product types
Actuation

Actuators

Rotary motion + the electric-actuator migration path — two products, two very different stories.

2 product types
Actuation

Cylinders

The linear-motion workhorse — eight cylinder types, one stroke-mount-load decision.

8 product types
Actuation

Vacuum End-Effectors

The pick-and-place sub-system — generate vacuum, grip the part, sense the cycle.

4 product types
Motion Control

Shock Absorbers

The deceleration layer — what catches the cylinder before it slams to stop.

2 product types
Motion Control

Speed & Flow Controls

How fast the actuator moves — meter the exhaust to set cylinder speed, throttle a line, hold a load.

3 product types
Sensing & Feedback

Sensors & Switches

The machine's eyes — confirm the motion happened, stream the state to the PLC.
