Description
B003308170056 Prefilter Assembly 41 CFM
The ELGi B003308170056 is a Pre-Filter accessory for compressed air systems. Proper filtration and separation help reduce particles, liquid water, and oil carryover that can damage tools, contaminate processes, and increase downstream maintenance.
Inline filters are commonly used to achieve targeted air quality levels by removing solids and aerosols in staged filtration (pre‑filter → fine/coalescing → optional activated carbon, depending on your application).
Key Features
- Staged filtration support: Helps build a filtration train that matches your air quality target (particles/water/oil).
- Protects downstream equipment: Reduces contaminants that can cause wear, sticking valves, and product quality issues.
- Serviceability: Designed for routine element replacement to keep pressure drop and air quality in control.
- System fit: Select by flow, connection type, and contaminant removal requirement for your application.
- Upstream protection stage: Pre‑filters help capture solids and bulk condensate to protect dryers and fine filters.

Benefits
- Improves equipment life: Cleaner air helps reduce wear, sticking controls, and premature tool failure.
- Supports consistent air quality: Filtration helps control particles, liquid water, and oil carryover in the air line.
- Helps reduce unplanned downtime: Contaminant control reduces maintenance events caused by sludge, corrosion, or wet air.
- Supports efficient operation: Properly maintained filtration helps minimize unnecessary pressure drop.
Installation & Application Notes
- Place filtration and separation stages in the recommended order: bulk separation/pre‑filter → dryer → fine/coalescing → optional carbon (if vapor removal is needed).
- Size the filter/separator for your actual airflow and pressure; undersizing increases pressure drop and service frequency.
- Route condensate drains to an appropriate collection/management system and check drain operation during commissioning.
- Monitor differential pressure (where applicable) and replace elements when restriction increases to maintain performance.
Frequently Asked Questions
B003308170056 Prefilter Assembly 41 CFM
▶️ Question: What’s the difference between a pre‑filter and a fine filter?
Answer: Pre‑filters are used upstream to capture solids and bulk condensate; fine/coalescing filters capture smaller oil and water aerosols that pass earlier stages.
▶️ Question: When would I add a carbon filter stage?
Answer: Use activated carbon downstream of coalescing filtration when you need to reduce oil vapor/odor—common for finishing processes, paint, and sensitive instrumentation.
▶️ Question: How do I size an inline filter?
Answer: Size for your maximum operating flow at pressure while keeping pressure drop acceptable. Oversizing generally reduces restriction and extends service intervals.
▶️ Question: Where should filters be installed relative to the dryer?
Answer: A pre‑filter is commonly installed before the dryer to protect it, and a fine/coalescing filter is installed after the dryer to capture aerosols and improve final air quality.
▶️ Question: What maintenance should I plan for?
Answer: Monitor differential pressure (if available), verify drain operation, and replace elements on a schedule based on contamination load and run hours.
