Pneumatic and Compressed Air Systems, Designed and Serviced
One team designs, installs, and services your pneumatics, from compressor room to cylinder rod.
Everything between the compressor and the tool
Pneumatic problems hide anywhere between the compressor room and the point of work. A perfect cylinder fed by a starved drop still runs slow. So we take the whole circuit as our scope:
- Circuit design: schematics, component sizing, and flow calculations before anything gets ordered.
- Cylinders and actuators: bore and stroke sizing, cushioning, rod alignment, and rodless or guided options where side load demands them.
- Valves and valve banks: single solenoids to full manifolds, with the correct Cv for the actuator they feed.
- FRLs: filtration, regulation, and lubrication at each drop, set for the tool, not the header.
- Vacuum: venturi and pump systems for pick and place and material handling.
- Compressed air piping and drops: headers, loops, and take-offs routed so the last machine on the run still sees stable pressure.
We work daily with SMC, Festo, Parker, and Norgren. We spec like for like on OEM machines, and we cross-reference obsolete parts to current equivalents, sized from bore, stroke, and mounting rather than a worn label.
Slow cycles, drift, and pressure drop
Most pneumatic complaints trace back to a short list of causes. A slow cylinder usually means a restricted flow control, an undersized valve, or leakage past the piston seals. Drift on a stopped cylinder points to worn seals or a leaking centre position on the valve. Good pressure at the compressor but low pressure at the machine points to undersized piping, a clogged filter element, or too many machines pulling from one drop.
We diagnose before we replace. Gauge readings at the FRL under load, not at idle. Cycle timing checked against the machine spec. Leak detection for the losses no one can hear over production. Then you get the repair versus replace math in plain terms. A seal kit on a large bore or specialty cylinder is often worth the labour. A seal kit on a small standard cylinder rarely is, because the rebuild costs more than the new part. We tell you which is which before the work starts.
Air supply, sized and kept clean
A pneumatic circuit is only as good as the air behind it. We size compressors against measured demand, not nameplate totals, because connected load and real draw are rarely the same number. We size dryers to the dew point the process needs. Refrigerated drying covers most plant air. Desiccant drying earns its cost where lines run through cold spaces or the product cannot tolerate moisture.
Filtration gets staged from coarse to fine and placed where it matters. For food plants, that means point-of-use treatment wherever air can contact product or packaging: coalescing and particulate stages, with oil-free or converter options where the process demands them. ISO 8573-1 gives the vocabulary for compressed air purity classes, and we spec against it, so your quality team gets a document instead of a promise.
Pneumatics that talk to your PLC
Modern valve banks are I/O devices, not just plumbing. Manifolds from SMC and Festo ship with communication modules for IO-Link, EtherNet/IP, and PROFINET. One network cable replaces dozens of discrete wires, and the PLC can see coil status, cycle counts, and diagnostics for every valve on the manifold. That data turns surprise failures into scheduled seal changes.
This is where a pneumatics vendor that also writes code earns its place. Bedford programs five PLC platforms: Allen-Bradley, Schneider, Omron, Phoenix Contact, and Unitronics. When we mount a networked manifold, we also address it, map the I/O, and write the ladder logic that runs it. You are not coordinating a pipefitter, a panel builder, and a programmer from three different companies for one valve bank.
One team from design to support
Pneumatics rarely fails alone. A sticking valve looks like a code fault. A dead solenoid looks like an electrical fault. In most plants that means three phone calls and two vendors pointing at each other while the line sits. Bedford is built to remove that problem. The same engineering-led team, with a B.Eng on staff, designs the circuit, builds the control panel in our own panel shop, writes the PLC code, and sends Red Seal industrial electricians to install and wire it.
One team for design, panels, code, install, and support means one point of accountability when a machine stops. Whoever picks up already knows your circuit, because we drew it.
Pneumatic service across the Maritimes
the Maritimes runs on compressed air. Seafood processors in Halifax and Charlottetown use it on packaging and processing lines where wet air near product is not an option. Sawmills and forestry operations around Truro and Amherst run gates, kickers, and sorters in dusty conditions that eat seals. Manufacturers in Moncton and Saint John push air through everything from presses to paint lines. The failure modes differ, but the arithmetic is the same: when the air stops, the plant stops.
Distance is the honest problem in this region. A specialist flown in from central Canada is a long wait when production is down. Bedford has people across the Maritimes and serves Halifax, Truro, Amherst, Moncton, Saint John, and Charlottetown. When a header lets go, call our emergency line, a real person will answer and we’ll get moving: 1-833-423-3367. It covers pneumatic and plant-air breakdowns.
