Large Size Air Treatment Combination Pneumatic Filter Regulator
SPFR Series large-flow air filter regulator lubricator unit is designed for stable and efficient compressed air treatment systems. Featuring a balanced pressure adjustment structure, it provides precise and reliable pressure regulation with excellent repeat accuracy. The specially designed internal guide structure improves air flow rotation, enabling efficient separation of water and solid particles for cleaner air output. The visible oil feeding design allows easy monitoring and stable lubrication performance. With durable construction, convenient installation, and optional 5μm or 40μm filtration precision, the unit is widely suitable for industrial pneumatic applications. Manual, differential pressure, and automatic drain options are available to meet different operating requirements.
