FEATURES AND APPLICATIONS OF WATTS HIGH EFFICIENCY FILTERS

Applications

• .3 µM Filter for protection highly sensitive pneumatic equipment (Logic, Bearings, High Speed Tools, Robotics).
• .7 µM Filter for general contamination removal in standard industrial applications.

Features

• Void volumes as high as 95% for maximum loading and long element life.
• Resin binder prevents media migration downstream.

Particulate Filters (F702)

• .9 µM absolute rating.
• 99.9% efficiency.
• Removes particulate contamination (rust, scale, dust) from compressed air lines.
• Used before a coalescing filters in systems with excessive liquid and particulate contamination.
• Place after desiccant dryer to prevent desiccant dust from migrating downstream.
• Pleated design provides large surface area for maximum particle retention capacity.

Absorber Filters (F702)

• Removes oils and hydrocarbon to .001 PPM
• Use to eliminate odors and hydrocarbon vapors.

(Note: Always place a .3µM coalescing filter before absorber.)

Absorber Filters

Note: To order filters with the factory installed pop up indicator, add suffix letter "P" to the model number. For example: F701-04 W3P

Flow ratings based on 100 psig inlet with a 1.5 psig pressure drop (dry condition:).

Differential Pressure Pop-Up Indicator

• Increase in pressure drop will cause orange piston to rise.
• A fully risen piston indicates the need to change filter element (12 PSI differential).
• Low cost method of monitoring pressure drop.
• 360° visibility.
• Available on coalescers only.
• Repair kit: RK701P
• Order factory installed only. Use suffix letter "P".

• Convenient method of monitoring pressure drop on filter already installed.
• Line mount.
• Readable both sides.
• 1/8" NPT female connections.
• Three color dial face.
• Order accessory: DP277WP

Differential Pressure Gauge
DP276WP

• Helps avoid contaminated air lines and poor equipment performance due to excessive pressure drop.
• Easy to read dial face indicates pressure drop and need for filter element replacement.
• Three color dial face.
• Green: 0-3 PSI (clean), Yellow: 4-8 PSI (change), Red: over 9 PSI (dirty)
• Readable from both sides.
• Non-pressurized dial face. Magnet operated.
• Low profile allows easy filter installations.
• High quality material construction for durability.
• Easily mounted in field using two brass bolts included
• Order accessory: DP276WP
