Raw compressed air straight out of compressors is never clean. It carries condensate water, solid particles, pipe rust and other impurities. Feeding this untreated air directly into cylinders, solenoid valves and air tools will cause seal abrasion, valve sticking, air leakage and unexpected downtime, raising your maintenance and replacement cost significantly.
That is exactly why reliable air‑preparation hardware — our SMC type s Aluminium Air Preparation Units — matters for every pneumatic workshop and automated production line.
Our modular air preparation portfolio covers full‑function F.R.L combination units (AC series), single air filter (AF), air regulator (AR), filter‑regulator two‑piece unit (AW), and separate lubricator (AL). All are built with die‑cast aluminum alloy housing, delivering stable performance for general‑purpose and tough‑condition industrial environments.
The whole series follows a modular concept, so you can select individual components or assembled combinations according to your actual air‑circuit requirements:
AF Air Filter: Remove solid particles and condensed moisture from compressed air. Filtration grades optional: 5μm /25μm /40μm. Manual drain or differential‑pressure auto‑drain is available.
AR Air Regulator: Accurately stabilizes output pressure within wide flow range, even under fluctuating inlet air pressure. Working pressure range: 0.05‑1.6 MPa.
AW Filter & Regulator (Two‑unit combination): Integrates filtration and pressure regulation in one compact body. Ideal for systems that need clean stable air without oil mist lubrication.
AL Lubricator: Adds fine oil mist proportionally into airflow, delivering lubrication for downstream pneumatic moving parts. Recommended oil: ISO VG32 turbine oil.
AC F.R.L Three‑unit Combination: Filter + Regulator + Lubricator all‑in‑one assembly. Complete air treatment solution for air tools, cylinders and valves requiring lubricated compressed air.
✅ Durable Die‑cast Aluminum Alloy Construction Main body adopts die‑cast aluminum alloy, featuring high‑pressure resistance, corrosion resistance, acid‑alkali resistance, and adapts to high‑low temperature working conditions. Operating temperature covers ‑5℃ ~ 60℃, D‑type option supports ‑40℃ ~60℃ for cold‑environment sites.
✅ Flexible Drain Options Manual drain (M) and differential‑pressure auto‑drain are both selectable. Auto‑drain frees operators from frequent manual water‑discharge work for 24‑hour non‑stop running equipment.
✅ Wide Port & Flow Selection Port sizes: G1/4, G3/8, G1/2, G3/4 (G‑thread). Covers models AC2000 / AC2010, AC3000 / AC3010, AC4000 / AC4010, rated flow from 500 L/min up to 4500 L/min, matching small‑size equipment to heavy‑duty pneumatic stations.
✅ Stable Pressure Performance Pressure regulation range: 0.05‑1.6 MPa (72.5‑232 psi); Max operating pressure:1.6 MPa; pressure resistance reaches 2.0 MPa (290 psi). Built‑in matching pressure gauge and L‑type mounting brackets for quick installation and real‑time pressure reading.
✅ Customization Supported We support customized requests for special working conditions. Contact our sales team for special temperature grade, filter precision and special configuration.
These air preparation assemblies are widely deployed across multiple industries:
Automated assembly production lines
Packaging & printing machinery
Woodworking equipment
Air‑tool workstations (impact wrenches, grinders, air drills)
General factory pneumatic control systems
Light‑industrial automation equipment
Practical Tip: If your downstream pneumatic components are oil‑free designed (self‑lubricated seals), choose AW filter‑regulator two‑unit combination, do NOT use lubricator. Lubricated oil mist will wash away built‑in grease and shorten component lifespan. Use full AC FRL three‑piece combination only when your cylinders or air tools require oil mist lubrication.
Take AC‑series FRL combination for example: AC 2000‑02 M
AC = FRL combination unit
2000 /3000 /4000 = body size
02(G1/4),03(G3/8),04(G1/2),06(G3/4) = port thread size
M = Manual drain; blank = differential‑pressure auto drain
For single units like AF filter, AR regulator, AW filter‑regulator, AL lubricator, the coding logic follows similar rules. Send us your port size, drain mode, temperature requirement and pressure requirement, and our team will recommend the correct model for you.
Many pneumatic failures root from poor air preparation, not defective cylinders or valves. Investing in high‑quality FRL / air preparation units helps you cut unexpected downtime, reduce spare‑part replacement cost and extend the whole pneumatic equipment’s service life.
Our AC‑series aluminium air‑preparation family provides flexible modular solutions: you can pick separate filter, regulator, lubricator or integrated combinations to fit your system layout.
