The JONELL Depth-LOK™ HT Series (JFGGF) is an elite filtration solution engineered for extreme thermal environments where standard filter elements fail. Designed specifically for high-temperature gas and liquid applications, the JFGGF series utilizes a specialized high-density glass fiber matrix bonded with high-temp resins to maintain structural integrity under intense heat.

By leveraging the Depth-LOK™ gradient density technology, these elements provide exceptional solid contaminant retention and extended service life in processes that demand continuous operation at elevated temperatures.

We warrants this part to meet or exceed OEM specifications, in Form, Fit, and Function,tested in accordance with ISO standards, with equivalent performance to original brands.

Application
Hot Gas Filtration: Removal of particulates from hot flue gases, exhaust streams, and catalyst recovery systems.

Refinery Fractionation: Filtering high-temperature feedstocks and process streams in distillation units.

Lube Oil Systems: Cleaning hot lubrication oils in turbines and large-scale industrial machinery.

Heat Transfer Fluids: Maintaining the purity of thermal oils and heat transfer fluids to prevent system fouling and efficiency loss.

Steam Filtration: Removing pipe scale and solids from high-temperature steam lines.

Chemical Processing: Handling aggressive chemical vapors and high-temperature reactants.

Extreme Temperature Resilience: Engineered to perform reliably in continuous service with temperature ranges 375 deg F to 500 deg F, far exceeding the limits of standard fiberglass or synthetic media.

Gradient Density Depth Loading: Features a tapered pore structure that captures larger particles on the outer surface and finer contaminants within the inner layers, maximizing dirt-holding capacity.

High-Temp Resin Bonding: The glass fibers are locked in place with a specialized thermosetting resin that prevents media migration and maintains pore stability at peak temperatures.

Rugged Mechanical Construction: Equipped with heavy-gauge stainless steel or carbon steel internal cores and end-caps to prevent collapse or bypass during high-pressure differentials.

Superior Chemical Compatibility: Naturally resistant to a wide range of corrosive chemicals, hot hydrocarbons, and aggressive process fluids.

No-Hole Metal Hardware: Available with various end-cap configurations (Bolt-on, Open End) to ensure a precision leak-proof seal in high-heat filter vessels.
