ASCO Numatics is introducing its 652 Series filter, regulator, and lubricator (FRL) line of air preparation products. The 652 Series features high flow characteristics and the widest high- and low-temperature ratings of any FRL - making it suitable for a broad range of applications.

Chris Walsh, UK Sales Manager for ASCO Numatics, says: “With the highest flow rates in the industry, our all-new 652 Series FRL assures original equipment manufacturers (OEMs) and maintenance managers that air preparation products from ASCO Numatics will optimise their machine performance. In addition, the 652 SeriesĀ“ extended high- and low-temperature capabilities (-40degC to 80degC) allow it to be specified across a broad range of applications, including those within harsh environments.”

These modular FRL products have a robust construction and are easy to assemble, mount, and position. In addition, their new manifold endplate flanges allow the maintenance technician to pull the manifold assembly out of service without disconnecting the piping. The product line is available in three port sizes ranging from 1/4 inch to 1/2 inch (NPTF, G, or R threads).

The 652 Series incorporates front-facing easy-to-read, low-profile gauges. It is the only product of its type to also offer these gauges on its shut-off isolation valves and slow-start/quick-exhaust valves. Optional integral pressure range indicators allow the user to easily set the red/green colour indicators to the desired pressure range. The 652 Series not only meets the need for a small footprint, but also results in clean lines and robust, modern-looking equipment.

An optional pressure regulator with reverse flow check permits the design engineer to place the regulator between the valve and cylinder. This allows air to be exhausted back through the regulator without causing damage or reduced life. In addition, an optional 3-micron pleated pre-filter has been added to the lineĀ“s coalescing filters and coalescing filter/regulator combination units. This filter eliminates the need for a separate particulate filter unit, reducing cost, size, and weight.

Walsh notes: “Our new air preparation products are the perfect fit for applications in the automotive and tyre, packaging, food and beverage, and process industries requiring high flow, wide temperature characteristics, highly reliable operation, and easy installation and service.”
