Understand the capabilities of Eaton’s bag filtration technology and how it can optimize your process, reduce downtime, and ensure product purity.
The Eaton GAF Legacy: Innovation in Filtration
Formerly known as GAF, Eaton’s filtration division pioneered the concept of the “bypass-free” filter bag. Today, Eaton GAF bags are engineered using advanced manufacturing techniques, such as 100% welded construction and the patented SENTINEL® seal ring. These innovations ensure that liquid cannot bypass the filter media, guaranteeing that the filtration efficiency you specify is exactly what you get.
Key Advantages
- Zero-Bypass Sealing: The pressure-activated SENTINEL® seal ring provides a seal that improves as the differential pressure increases.
- Welded Construction: Unlike sewn bags, welded seams eliminate needle holes where particles can escape, providing superior filtration consistency.
- Silicone-Free Options: Essential for automotive paint and varnish applications to prevent cratering.
- Extended Service Life: Advanced media designs (like the HAYFLOW and MAX-LOAD series) offer significantly higher dirt-holding capacities than standard bags.
Eaton GAF Product Series Guide
Eaton offers a diverse portfolio of filter bags, each tailored for specific filtration challenges. Below is a guide to selecting the right series for your application.
| Product Series | Filtration Type | Efficiency | Best For |
|---|---|---|---|
| PROGAF™ | Absolute (Depth) | Up to 99.98% | High-purity fluids, pharmaceutical, food & beverage. Acts as a cartridge replacer. |
| ACCUGAF™ | High Efficiency | >99% | Beer, wine, spirits, hydraulic oils, and parts cleaning fluid. |
| LOFCLEAR™ | Specialty / Oil Removal | >99% | Oil adsorption from water, electro-coating paints, gelatinous contaminants. |
| HAYFLOW™ | High Capacity Element | Nominal | High-flow applications. Offers up to 65% more surface area than standard bags. |
| MAX-LOAD™ | Depth | Nominal | High dirt-holding capacity for retention of deformable gels and hard particles. |
| SENTINEL® | Surface (Monofilament) | Nominal | General purpose paints, inks, resins, and water purification. |
Detailed Product Breakdown
1. PROGAF™: The Cartridge Alternative
The PROGAF™ series revolutionizes bag filtration by offering efficiencies of up to 99.9% at 1 micron. Constructed with a multi-layer progressive density depth media, it bridges the gap between bag filters and cartridge filters. This makes it an economical choice for applications requiring absolute filtration without the high cost of cartridges.
2. LOFCLEAR™: Mastering Gel and Oil Removal
LOFCLEAR™ 100 series bags feature a unique multi-layer construction designed for high-purity fluids. They are particularly effective at removing deformable particles (gels) that standard bags might release under pressure. Additionally, LOFCLEAR™ 500 bags are engineered specifically for oil absorption, capable of holding significant amounts of oil weight, making them ideal for degreasing and environmental remediation.
3. HAYFLOW™: Extended Life and Flow
The HAYFLOW™ element combines the best features of a filter bag and a filter cartridge. By using a pleated geometry, it increases the filter surface area by 65% within a standard bag housing. This results in:
- Longer intervals between filter changes (reduced downtime).
- Lower filter consumption and disposal costs.
- Compact filtration systems with higher flow rates.
Material Specifications and Chemical Capability
Choosing the correct material is critical for process compatibility. Eaton GAF bags are available in a variety of materials to suit different chemical and thermal environments.
| Material | Max Temperature | Swell Resistance | Acid Resistance | Alkali Resistance |
|---|---|---|---|---|
| Polypropylene (PO) | 200°F (93°C) | Excellent | Excellent | Excellent |
| Polyester (PE) | 300°F (149°C) | Good | Good | Fair |
| Nylon (NMO) | 250°F (121°C) | Excellent | Fair | Good |
| Teflon / PTFE | 500°F (260°C) | Excellent | Excellent | Excellent |
Applications by Industry
Eaton’s diverse range of filter bags ensures optimal performance across various sectors:
- Food & Beverage: Removal of particles from beer, wine, and edible oils using FDA-compliant materials (ACCUGAF, PROGAF).
- Automotive: Filtration of E-coat paints, clear coats, and solvents where silicone-free construction is mandatory (LOFCLEAR).
- Water Treatment: Protection of Reverse Osmosis membranes and resin beds by removing suspended solids (SENTINEL, MAX-LOAD).
- Chemical Processing: Filtration of acids, alkalis, solvents, and amine solutions.
- Metal Working: Filtration of cutting fluids, hydraulic oils, and parts washing solutions.
