Prep Air II FAB’s • • • • • • • • • • • 2

High Flow Elements Threaded Collar Domestic Manufacturing Superior Factory Deliveries Best Auto Drain in Industry Stainless Steel Low Temperature Precision (various levels) Sensor Options Dial Air Full offering of accessories

What To Look For… • For Filters: Filter rating, Flow, Pressure, Drain type Pipe size is not right size!! Do they need metal bowls? If so why? Any Problems: Water in lines, large pressure drops, etc. • Service schedule? Element changes!! • • • •

3

What To Look For… • For Regulators • • • • • • • • 4

Pressure range for inlet and outlet Do they use a gauge? Sensors?? Flow needed Accuracy (std. vs. precision) Adjustment type (knob or t-handle) Relieving or Non-Relieving Can they use a piggyback Reverse Flow

What To Look For… • Lubricators What are they lubricating How much lubrication is needed How far away will the lubricator be Type of oil used – F442 vs. Marvel Mystery Oil • Do they even need a lubricator? • • • •

Best Pneumatic Practices - General

Air

Cost Facts • Compressed air cost is six times greater to produce 1 HP of pneumatic energy verses 1 HP of electrical • As much as 25% of air cost in a plant can be associated to simple leaks • 2 PSI reduction in air pressure equates to 1/4 HP cost reduction in electricity • 1 cfm =1/4 HP =.207Kw@$.06/kwh = $110/yr • Higher the operating pressure higher the cost • Compressor efficiency can be as low as 65%, and run continuous in most facilities.

Best Pneumatic Practices - Leaks You Hear • • • • •

Fittings on air prep, valves, cylinders Rod glands on cylinders (retracted) Vacuum generators Blow off applications Valve gaskets and other seals

Best Pneumatic Practices- Air Leakage Rates and Cost • • • • •

8

($0.24/MCF 8,760 Hrs/Year @ 100 PSIG)

1/16” Diameter leak = 6.5 CFM = $800 1/8” Diameter leak = 26 CFM = $3,208 1/4” Diameter leak = 103 CFM = $12,812 3/8” Diameter leak = 234 CFM = $29,113 (Vacuum and blow off typical @ 1/4” and 3/8” rates)

Best Pneumatic Practices - Leaks You Don’t Hear • • • •

9

Leaky fittings and connectors Leaking cylinder piston seals Excessive pressure and regulation (relieving) Leaky directional valve spool designs

Best Pneumatic Practices - Reverse Flow Regulators • Piped between valve and cylinder provides independent pressure control for extend and retract • Provides reverse flow at high flow rate without reverse check valve • Non relieving design saves air and wear on components and mechanical devices

(Not So) Best Pneumatic Practices Lapped Spool • • • • • •

11

Leakage rate new from 25-55 sccm* Air cost per year static $150 Matched sets High replacement cost Leakage rate 5 million cycles 236-871 sccm Air cost per year static $2,400

Best Pneumatic Practices - WCS Spool Design • • • • • • • •

12

Leakage rate 0 sccm* Air cost per year static $0 Single slip in replacement spool Fast Response & Low Friction Lowest cost of any spool design Leakage rate 5 million cycles 0-25 sccm Air cost per year static $100 Under pressure, radial expansion of the seal occurs to maintain sealing contact with the valve bore.

Best Pneumatic Practices - Critical Considerations/Cost of Ownership • Proper sizing of components reduces capitol and replacement costs and optimizes system efficiency. DO NOT oversize. • Utilize smart air prep systems that provide adequate flow and PM detection devices. • Specify valve products that provide leak free spool technology and low wattage coils. • Upgrade cylinders that provide repairable rod glands. • Replace leaking seals on actuators • Implement cycle timing controls on blow off applications to reduce operating costs. 13

Best Pneumatic Practices - Design Considerations/Cost of Ownership Cont. • Reverse flow regulators. Most actuators do work in only one direction. • Shut off air when not in use. • Reducing required operating pressure saves money on air, as well as, wear and tear on machine components and seals. • A combination of smart engineering, zero leakage products, and application of Best Pneumatics Practices will provide your customer with a cost effective, cost reduced solution for their equipment, thus differentiating you from the competition. 14

Flow - Example

15

Elements • Large element surface area allows: • Greater retention of contamination • Longer element service life • Less pressure drop for a rated flow

• Parker 06F element has 39% more surface area than Norgren 73

16

Quality and Design Advancements 05F - Auto Drain redesign 05R - Poppet stiction issue 14R - Knob color (yellow/black) 05S - Internal design change after moving mfg. to PDN from Cannock • PSI semi precision regulator soon to become standard product offering. • Parker offers RoHs certification upon request. • Element color change (speckles vs. solid) • • • •
