Product Description
Replacement JOHNSON Oil Separator Coalescers filter 1517.079 1517-079
LEFILTER 1517.079 replacement filter elements are manufactured using the highest quality materials and workmanship. This coalescing filter provides the same or better filtration performance as the original factory filter element.
Coalescing filters, also known as air-oil separators, are used to remove water, oil vapor, and other contaminants from compressed air lines. These coalescing filters provide the highest level of clean compressed air with minimal pressure loss. Our coalescing filters are strong enough to hold their shape under pressure and maintain a uniform pressure differential to avoid element collapse.
Model: 1517.079
Filtration accuracy: 3um
Filter media: air, oil
Filter element type: Air compressor precision filter element

FAQ
Q1: What is the purpose of an air compressor filter element?
A: The filter element removes contaminants (like dust, dirt, oil aerosols, water vapor, and sometimes microbes) from the compressed air stream. This protects downstream equipment, ensures air quality for applications, and improves efficiency.

Q2: How often should I replace my air compressor filter element?
A: Replacement intervals vary significantly based on compressor usage, air quality demands, environmental conditions, and filter type. Always consult your compressor manual and monitor the differential pressure gauge. Typical ranges are every 3-6 months or 1000-8000 operating hours, but it could be more frequent in harsh environments.
Q3: What are the signs that my filter element needs replacing?
A: Key signs include:
A significant increase in pressure drop across the filter (shown by the differential pressure gauge nearing or exceeding the max recommended level).
Visible contamination downstream (e.g., water, oil, or dirt in tools/equipment).
Reduced airflow or compressor performance.
Physical damage to the filter housing or element.
Reaching the manufacturer's recommended service interval.
Q4: What are the signs that my filter element needs replacing?
A:  Increased Energy Consumption: A clogged filter causes higher pressure drop, forcing the compressor to work harder.
Reduced Airflow & Performance: Lower pressure and flow reaching tools/equipment.
Contaminated Air: Dirt, water, and oil damage downstream equipment (pneumatics, valves, tools, instruments), ruin products (painting, food), and pose health risks.
Potential Filter Failure: A severely overloaded element can rupture, releasing trapped contaminants into the air line.
Increased Wear: Contaminants cause abrasion and corrosion in the compressed air system.
Q5: Can I clean and reuse my air compressor filter element?
A: Generally, NO. Most standard filter elements (especially coalescing and particulate) are designed for single use. Cleaning attempts (like blowing with compressed air) are ineffective, damage the delicate media, and can push contaminants deeper into the filter. Only specific, cleanable pre-filters might be reusable
