Product Description

Product Description

DFO-629PLF10 aviation fuel pre-filter element SO-318C SO-318V SS656FF SO656V

Lefilter Replacement DFO Series Particulate Filters deliver high-quality filtration for diesel and biodiesel applications.

From refining to distribution, diesel undergoes multiple stages of storage and transportation. Preventative measures cannot entirely eliminate contamination. Common contaminants introduced during transit include extremely fine and abrasive silica as well as pipeline scale deposits. These pollutants rapidly degrade fuel quality below engine manufacturers' specifications, compromising engine durability and performance. Lefilter's design balances high surface area combined with depth filtration, thereby maximizing filter element service life and reducing filtration costs.

Application:
• Fuel Reception
• Bulk Fuel Storage
• Fuel Dispensing

Specification

Recommended changeout differential pressure	25 psid
Media material	Pleated Filter Paper
Micron ratings	from 2 to 40  / 98%+ Nominal filtration efficiency
Operating pH range	5-9
Flow rate	depends on the fluid

Product Advantages

• Reduced operating costs by removing particulates that can cause engine damage
• Reliable fuel injector performance when particulate contaminants are removedto meet ISO 4406 Cleanliness Standards
• Improved equipment uptime, reduces equipment failures, repairs, and/or replacements

Product Features

• Large Surface Area – Allows high flow rate with low initial pressure drop and maximum contaminant holding capacity.

• 75 PSI Collapse Strength – Heavy gauge carbon steel center tubes give safety margin against pressure surges.

• Corrugated Media – More surface area ensures longer service life.

• Thermoset Bonding Material – Durable endcap-to-media bond prevents internal bypassing

• These are also available in screw-base design

FAQ

1.Q: What is the primary function of a coalescing separator filter?
A: It removes emulsified and free liquids (e.g., water, oils) from gases or fuels by merging fine droplets into larger ones ("coalescing"), then separating them via gravity/barrier mechanisms.

2.Q: How does coalescing differ from standard particulate filtration?
A: Coalescers capture sub-micron liquid aerosols via depth media (e.g., glass fiber), causing droplets to merge; particulate filters trap solids via surface capture. Coalescers require downstream separation stages.

3.Q: Which materials are optimal for aggressive chemical applications?
A:Media: Borosilicate glass fiber (hydrocarbons), PTFE membrane (acids, solvents)
Hardware: 316L stainless steel housings, FFKM seals
Avoid cellulose in pH-extreme environments.

4.Q: Why is differential pressure (ΔP) critical for coalescers?
A: High ΔP (>5-7 psi) collapses media pores, causing:
Reduced efficiency,Media migration,Structural failure
Monitor ΔP continuously; replace at 25% above clean ΔP.

5.Q: How does flow rate impact coalescer performance?
A: Exceeding rated flow:
Reduces dwell time → poor droplet merging, Increases reentrainment risk,Shortens lifespan, Always size for peak + 15% safety margin.
