Absolute Precision in Industrial Liquid Filtration
For industrial applications requiring high purity and absolute filtration efficiency, standard needle felt bags often fall short. The Eaton LOFCLEAR™ Filter Bag series allows industries to bridge the gap between cost-effective bag filtration and high-performance cartridge filtration. Available through Purecowater, these filter bags are engineered to deliver absolute efficiency ratings ranging from 95% to 99%, making them an ideal solution for critical process fluids, paints, coatings, and water treatment.
The LOFCLEAR line is divided into two distinct series—the 100 Series and the 500 Series—each designed to tackle specific filtration challenges, from oil removal to high dirt-loading capacity.
LOFCLEAR™ 100 Series: High Purity & Oil Removal
The LOFCLEAR 100 Series utilizes superior meltblown polypropylene technology. Unlike standard bags, the 100 Series features a multi-layer construction that provides depth filtration with absolute accuracy. These bags are specifically designed for applications where high purity is non-negotiable, such as in the automotive industry for electro-coating or in food and beverage processing.
Key Features of Series 100
- Multi-Layer Construction: Triple-layer pure polypropylene meltblown media ensures high efficiency.
- SENTINEL® Seal Ring: Patented sealing ring prevents fluid bypass, ensuring 100% of the fluid passes through the filtration media.
- Oil Adsorption: Specific models (LCR-118/119/128/129/130) are designed to absorb oils from water or other fluids.
- Silicone Free: Manufactured without silicone oils or lubricants to prevent cratering in paint and coating applications.
| Model | Efficiency (>99%) | Primary Application |
|---|---|---|
| LCR-113 to 116 | 4 µm – 15 µm | High Purity Fluids, Acids, Solvents |
| LCR-123 to 126 | 4 µm – 15 µm | General Absolute Filtration |
| LCR-118/119 | 30 µm – 40 µm | Oil Removal & Adsorption |
| LCR-128/129 | 30 µm – 40 µm | Automotive E-Coat, Oil Removal |
LOFCLEAR™ 500 Series: Extended Life & Gel Retention
The LOFCLEAR 500 Series represents a significant advancement in bag design. It features a fully-welded, multi-pleated construction that dramatically increases the surface area compared to standard bags. This design creates a “bag within a bag” effect, offering exceptional dirt-holding capacity (up to 1,000g or 2.2 lbs) and the ability to capture deformable particles like gels.
Key Features of Series 500
- Pleated Pre-Filter: Provides approximately 32 square feet of filtration surface area.
- Gel Removal: The complex tortuous path of the media is excellent for retaining gelatinous particles.
- Long Service Life: High dirt-holding capacity results in fewer change-outs and lower operational costs.
- Heavy Duty Construction: All-welded polypropylene guarantees mechanical strength and zero efficient bypass.
| Model | Absolute Rating (99%) | Description |
|---|---|---|
| LCR-522 | 2.6 µm | Ultra-fine filtration for critical slurries |
| LCR-525 | 6.0 µm | Fine filtration for coatings and resins |
| LCR-527 | 13.0 µm | General chemical & water processing |
| LCR-529 | 32.0 µm | Pre-filtration and bulk solids removal |
Technical Specifications Overview
Both series utilize 100% pure polypropylene materials, ensuring broad chemical compatibility with acids, alkalis, and solvents. The absence of bonding agents or adhesives ensures that the filtration process remains pure and does not introduce downstream contaminants.
- Material: Meltblown Polypropylene (100 Series) / Pleated Polypropylene (500 Series)
- Max Operating Temperature: 194°F (90°C)
- Max Differential Pressure: 36.2 psi (2.5 bar)
- Seal Configuration: SENTINEL® Polyloc Ring (fits standard housings)
- Flow Rates: Up to 53 GPM (Size 02, 500 Series) depending on viscosity and micron rating
Who Should Use LOFCLEAR™ Filter Bags?
These filter bags are engineered for industries where fluid quality directly impacts product value. They are extensively used in:
- Automotive Manufacturing: For filtration of Electro-Coats (E-Coat), clear coats, and surface treatments.
- Chemical Processing: For filtering acids, alcohols, and high-purity solvents.
- Food & Beverage: (Specific FDA compliant models) For filtering edible oils, syrups, and process water.
- Oil & Gas: For amine sweetening and glycol dehydration fluids.
- Paints & Coatings: To remove gels and agglomerates without stripping vital resins.
