Humphrey Cylinder HNSA10×1/4
Humphrey (Hanfrey) is a century-old American pneumatic brand (established in 1901), specializing in the research and development of high-performance pneumatic components. The HNSA series of cylinders are renowned for their stainless steel construction, corrosion resistance, and modular design, making them suitable for demanding industrial environments such as food processing, pharmaceuticals, and automotive manufacturing.
I. Core Design Features
Material and Structure
• All-stainless steel construction: The cylinder body is made of 304 stainless steel (stretched and polished), while the piston rod is crafted from 303 stainless steel, offering far superior corrosion resistance compared to ordinary carbon steel cylinders. This makes them ideal for humid and chemically corrosive environments (e.g., food processing and marine equipment).
• Magnetic piston design: Built-in magnetic pistons support non-contact position detection (compatible with magnetic switches), enabling precise travel control.
• Unrestricted port design: Large-flow air passages reduce airflow resistance and enhance response speed (approximately 15% improvement in piston smoothness).
Installation and Compatibility
• Compact interface: The interface size is 1/4 inch (NPT threaded standard), compatible with mainstream pneumatic piping systems and supporting quick installation.
• Interchangeable design: Fully compatible in size with Fabco-Air H series and competing cylinders, allowing direct replacement of older models and reducing maintenance costs.
Typical Application Scenarios
Food and Pharmaceutical Equipment
• Valve control in filling machines and positioning of packaging robotic arms, utilizing oil-free lubrication design to prevent media contamination and comply with FDA/GMP standards.
Automotive Manufacturing Lines
• Actuation of welding robot fixtures and assembly of engine components, relying on high repeat positioning accuracy (±0.1 mm).
Marine and Chemical Equipment
• Actuators for desalination valve groups and control of corrosive media conveyance, with stainless steel construction resistant to salt spray and chemicals.
