Product Overview

The ROSS Controls High-Capacity Series is a heavy-industrial Filter Regulator Lubricator (FRL) combination product line for 3/4" to 1-1/2" port size compressed air systems. The High-Capacity Series delivers combined filtration, pressure regulation, and lubrication with maximum flow capacity up to 495 scfm (14018 l/min), making it the appropriate selection for plant-level main air preparation, large machine air supply stations, and centralized FRL installations serving high-demand compressed air systems.

The High-Capacity Series FRL components are offered individually as a filter, regulator, and lubricator, and are designed for inline mounting to form a complete high-flow air preparation station. Individual components can also be installed as standalone units where only a single air treatment function is required at the specified port size and flow rate.

The filter component is available with high-strength polycarbonate plastic bowls with steel shatterguard or metal bowls with clear nylon sight glass. The High-Capacity Series extends the drain options to include internal automatic drain, manual drain, external automatic drain, and electronic drain, providing the most comprehensive condensate management range in the ROSS Controls FRL product line. The piston-type regulator provides robust high-flow pressure regulation with self-relieving or non-relieving function.

The lubricator is available in both wick-feed and sight-feed designs, giving engineers the choice between tamper-resistant internal oil delivery (wick-feed) and visible adjustable oil injection (sight-feed) based on application monitoring requirements. The High-Capacity Series is the definitive selection for main plant air preparation headers, industrial compressor system air treatment, large pneumatic presses, and heavy-duty industrial machinery with 3/4" to 1-1/2" supply connections.

Key Engineering Features

Frequently Asked Questions (FAQ)

Q: What is the maximum flow capacity of the High-Capacity Series FRL?

A: The High-Capacity Series delivers maximum flow of 495 scfm (14018 l/min) at port sizes from 3/4" to 1-1/2".

Q: What port sizes are available?

A: The High-Capacity Series is available in 3/4", 1", 1-1/4", and 1-1/2" NPT port sizes.

Q: What is the difference between wick-feed and sight-feed lubricators in the High-Capacity Series?

A: The wick-feed lubricator uses an internal absorbent wick to deliver oil into the compressed air stream. The delivery rate is adjusted internally, providing a tamper-resistant oil delivery mechanism. The sight-feed lubricator has an external sight tube or window through which oil droplets entering the air stream are visible, allowing direct observation and adjustment of the delivery rate during normal operation. Select sight-feed when visual confirmation of lubrication is required; select wick-feed for tamper-resistant applications.

Q: What is the external automatic drain?

A: The external automatic drain uses a float mechanism inside the filter bowl to trigger a valve that expels condensate through an external piped outlet rather than discharging directly below the filter. This allows condensate to be piped to a remote drain location, which is essential for overhead-mounted FRL installations, enclosed enclosures where floor drainage is not available, or applications where condensate must be collected for disposal rather than discharged at the filter location.

Q: What is the maximum operating pressure of the High-Capacity Series?

A: Maximum operating pressure is 150 psig (10 bar) for units with polycarbonate bowls and 250 psig (17 bar) for units with metal bowls. The 250 psig metal bowl rating is the highest in the ROSS Controls FRL product line.

Q: When should I select the metal bowl over the polycarbonate bowl?

A: Select the metal bowl when operating pressure exceeds 150 psig (requiring the 250 psig-rated metal bowl), when ambient temperature exceeds 125 degrees F (metal bowl rated to 150 degrees F), or when the installation environment involves significant mechanical impact hazard, chemical splash, or aggressive conditions where polycarbonate bowl integrity may be at risk.

Q: Is the High-Capacity Series designed for modular or inline mounting?

A: The High-Capacity Series is designed for inline mounting. Each component is installed directly in the compressed air supply line using the port connections, with the pipe providing the primary mechanical support. This differs from the modular mounting approach of the mid-size and full-size series.

Q: What temperature range is the High-Capacity Series rated for?

A: Polycarbonate bowl units are rated for 40 to 125 degrees F (4 to 52 degrees C). Metal bowl units are rated for 40 to 150 degrees F (4 to 66 degrees C).

Q: What type of regulator does the High-Capacity Series use?

A: The High-Capacity Series uses a piston-type regulator. Piston-type designs are well-suited for high-flow applications where robust mechanical regulation performance and resistance to high differential pressure are priorities. Self-relieving is standard; non-relieving is available as an option.

Q: Can I install just a filter or just a regulator from the High-Capacity Series?

A: Yes. Each filter, regulator, and lubricator component is available as an individual unit. They can be installed as standalone components or combined into a complete three-unit FRL inline assembly.

Q: What filtration grades are available for the High-Capacity Series filter?

A: The High-Capacity Series filter is available with 5-micron and 40-micron particulate removal elements. For applications requiring oil aerosol removal, coalescing elements are available. Consult the ROSS Controls catalog or contact ROSS at (800) 438-7677 for available filtration grades at each port size.

Q: How often should the High-Capacity Series filter element be replaced?

A: Replace the filter element when the differential pressure across the filter reaches the service threshold specified in the ROSS Controls catalog or installation instructions for the High-Capacity Series. In high-contamination environments, inspect more frequently. Install a differential pressure gauge across the filter to enable condition-based element replacement.

Q: Are catalog drawings and technical data available?

A: Complete catalog part numbers, dimensional drawings, and technical data for the High-Capacity Series are available at rosscontrols.com. Contact ROSS Controls at (800) 438-7677 for configuration and technical support.

Installation & Maintenance Guidelines

Mount the High-Capacity Series FRL components with the bowls in the downward (vertical) position to allow condensate to collect at the drain for proper expulsion.
Support the FRL assembly with appropriate pipe support brackets or mounting hardware at 1" and larger port sizes where the component weight and pipe diameter require additional mechanical support beyond the threaded pipe connection.
Install components in the correct flow sequence: filter (inlet) - regulator (middle) - lubricator (outlet).
Verify that the flow direction arrow on each unit body is aligned with the compressed air flow direction before making port connections.
Apply PTFE thread sealant or pipe thread compound appropriate for compressed air service to all NPT connections. Tighten to the torque specified in the ROSS Controls installation instructions.
For 1" and larger port connections, ensure that the upstream piping is adequately supported to avoid imposing bending loads on the FRL component bodies.
Pressurize the system gradually and inspect all port connections and bowl seals for air leakage with an approved leak detection solution.
For external automatic drain installations, connect the drain outlet to an appropriate piped drain or condensate collection system. The drain line must be free-draining with no restrictions that would prevent condensate expulsion.
For electronic drain installations, configure the timer or demand controller per the application condensate volume and the drain controller installation instructions.
Set regulated output pressure on the piston regulator by unlocking the adjustment knob, rotating to the target pressure on the gauge, and locking the knob at the set point.
Select and install the appropriate lubricator (wick-feed or sight-feed) per the application lubrication monitoring requirements. Fill the bowl to the maximum fill level with recommended petroleum-based oil (ISO 32 or lighter).
For sight-feed lubricators, adjust the needle valve to the desired delivery rate while observing the sight tube. Typical starting rate is approximately one drop per minute per 5 to 10 scfm of downstream air consumption.
Replace filter elements at the specified differential pressure threshold or scheduled maintenance interval. Shut off inlet pressure and depressurize the system before removing the bowl for element replacement.
