Save on Energy Consumption and Cost with the New Range of Air Preparation Products from Emerson

The ASCO Numatics™ Series 653 air preparation products suitable for applications where high-flow-rate is required

Florham Park, NJ, (June 18, 2018) — Emerson announces the introduction of its ASCO Numatics Series 653 air preparation products. Available in ½-inch, ¾-inch and 1-inch port sizes, the Series 653 has a high flow rate for its size.  This enables customers to power more products from the same Filter-Regulator or Lubricator (FRL), or reduce pressure drop across the system, both of which enable potential energy and cost savings. The range of the Series 651, 652, and 653 products consists of filters, regulators, filter regulators, lubricators, soft starts, quick exhausts, diverter blocks and shut off valves.

“The introduction of our Series 653 products greatly expands our global offering of high-flow air preparation products,” said Scott Weickel, Vice President of Engineering for Machine Automation applications at Emerson. “The addition of the new port sizes enables international manufacturers to select a comprehensive range of advanced technology air preparation products, in sizes ranging from 1/8-inch to 1-inch, all from one supplier. This makes selection and purchasing simpler.”

With the industry’s highest flow characteristics, related to size, the ASCO Numatics Series 651, 652, and 653 products are ideal for use in any application that requires high volumes of air or where space is limited.  Original equipment manufacturers will benefit from the wide temperature range (-40°C to 80°C), and ATEX and CUTR certification, which enable the products to be used in challenging and harsh environments, and applications such as valve piloting in the process industry. The modular air preparation products have a robust construction and are easy to assemble, mount, and position. New endplate flanges allow the removal of the manifold assembly without disconnecting the piping.

The Series 651, 652, and 653 products incorporate front-facing easy-to-read, low-profile gauges. Optional integral red/green pressure range indicators make it easy to monitor the desired pressure. The small footprint and clean lines help achieve robust, modern-looking equipment. Long-lasting laser-etched tags and covers ensure product information will remain visible even in challenging - environments.  In addition, an optional 3-micron pleated pre-filter has been added to the line’s coalescing filters and coalescing filter/regulator combination units. This eliminates the need for a separate particulate filter unit and reduces cost, size, and weight.
