A.P.I. Series M and MX compact micro-cylinders built to ISO 6432 and CETOP RP 52 P standards deliver high-speed precision positioning, component clamping, and rapid indexing in compact packaging machinery and electronics assembly.
The standard Series M features a rolled stainless steel barrel with anodized aluminum end caps (bore sizes 8, 10, 12, 16, 20, and 25 mm), while the all-stainless Series MX constructed from AISI 316 provides complete sanitary integrity and corrosion resistance during frequent CIP/SIP caustic washdown procedures.
Specify bore size (8–25 mm), stroke length, action type (single/double), magnetic ring option, and mounting accessories.
ISO 21287 Compact Cylinders CI and CIX Series
A.P.I. Series CI and CIX compact short-stroke cylinders conforming to ISO 21287 are engineered for robotic end-effectors, stamping dies, clamping jigs, and space-critical machinery.
The low-profile monolithic body saves up to 50% axial envelope length compared to standard ISO 15552 cylinders while maintaining high thrust forces.
The CI series is produced in extruded aluminum with bore sizes 20–100 mm featuring female/male rod threads and dual anti-rotation guide rods, while the CIX series in AISI 316 serves corrosive and sterile environments.
Selection parameters: bore diameter (20–100 mm), stroke length (5–100 mm), rod thread type, and anti-rotation option.
Rodless Cylinders Series S and Guided Units BG/UG
A.P.I. Series S long-stroke rodless pneumatic cylinders and heavy-duty guided linear modules BG/UG are engineered for Cartesian gantries, material handling transfers, and automated sorting conveyors.
The Series S mechanical slotted-barrel actuator enables payload transport across travel distances up to 6000 mm without rod deflection, while BG integrated slide modules and UG modular bolt-on guide frames absorb high radial moments and torsional shock loads.
Specify cylinder bore (16–63 mm), stroke length up to 6000 mm, carriage load ratings, and external guide rail type.
AISI 316 Stainless Steel Pneumatic INOX Line
The complete A.P.I. INOX Line pneumatic automation portfolio is fabricated from premium corrosion-resistant austenitic stainless steel AISI 316 (EN 1.4401) and AISI 316L (EN 1.4404).
The product line includes MDX (ISO 15552), MX (ISO 6432), CIX (ISO 21287), and RX cylinders, AX/A1X directional control solenoid valves, CX modular FRL air preparation units, and AISI 316L push-in fittings.
All components hold ATEX hazardous-area explosion-proof certifications and provide maximum longevity in chemical, offshore, and food manufacturing cleanrooms.
Pneumatic Directional Control Valves A1, ME, and NAMUR Series
A.P.I. Series A1 and ME electro-pneumatic and pneumatic directional control valves and NAMUR interface valves provide dependable switching control for linear actuators and rotary process valve actuators.
The lineup encompasses balanced spool valves Series A1 (3/2, 5/2, 5/3 functions with G1/8, G1/4, G1/2 ports), direct-acting ME micro-valves, NAMUR (VDI/VDE 3845) direct-mount quarter-turn valve controllers, and ISO 5599/1 sub-base valves compatible with DC and AC solenoid coils from 12V to 230V.
Specify valve function (3/2, 5/2, 5/3), port thread size, coil operating voltage, and NAMUR/sub-base mounting standard.
Air Preparation FRL Modular Units C and CX Series
A.P.I. Series C modular FRL air preparation systems and CX stainless steel assemblies deliver high-efficiency moisture removal, particulate filtration, precise line pressure regulation, and controlled aerosol lubrication for downstream actuators.
The modular interlocking architecture enables versatile combinations of filter-water separators (5 µm and 20 µm), relieving diaphragm pressure regulators, 0.01 µm micro-coalescing filters, and proportional mist lubricators spanning G1/8 to G1" ports with air flow capacities up to 5000 Nl/min.

Engineering Selection and Pneumatic Circuit Verification
Our engineering team performs thrust force calculations, cycle speed sizing and compressed air consumption audits to specify the exact A.P.I. component configuration for your automation machinery.
For standard automation tasks, we calculate bore sizes and stroke requirements for Series MD and MS cylinders conforming to ISO 15552.
For demanding food processing, chemical and pharmaceutical cleanrooms, we verify chemical compatibility across the all-stainless INOX Line (AISI 316 / EN 1.4401 and 1.4404) with FKM Viton or FDA-compliant elastomer seals.
For directional control valves, we verify electrical coil voltages, NAMUR interfaces and ATEX compliance ratings, while sizing FRL air prep units to guarantee air purity classes according to ISO 8573-1.
Industrial Standards and Operational Applications
A.P.I. pneumatic components are engineered for continuous high-cycle reliability in heavy-duty automated manufacturing environments in accordance with ISO 15552, ISO 6432, ISO 21287, ATEX directives and ISO 9001 quality management systems.
These motion systems operate across food and beverage packaging lines, conveyor sortation hubs, robotic assembly cells, CNC machining fixtures, woodworking centres, chemical processing units and offshore marine platforms requiring robust corrosion resistance.
