DRISORB™ Gas Phase Honeycomb Chemical Filters

High-Efficiency Dry Chemical Filtration for Critical Air Quality Applications

DRI’s DRISORB™ Gas Phase Honeycomb Filters are advanced dry chemical filtration solutions designed to effectively remove corrosive, toxic, and odorous gaseous contaminants from air streams. Built on a high-strength macroporous honeycomb matrix, DRISORB filters combine insoluble metal silicates and activated carbon, enhanced with carefully selected oxidising and alkaline impregnates for superior contaminant removal.

Engineered for high airflow operation, these filters deliver exceptional efficiency while maintaining very low pressure drop, making them ideal for installations with space limitations and high air volume requirements.

Technical Specifications

Advanced Honeycomb Filter Media Technology

The DRISORB™ media uses in-situ synthesized and deposited impregnation technology, ensuring uniform distribution of active chemicals throughout the honeycomb structure. This design provides consistent performance, high reliability, and extended service life compared to conventional loose-fill or granular media filters.

Key Media Features

High bulk density > 320 kg/m³ (> 20 lb/ft³) for enhanced adsorption capacity
Honeycomb monolith media available in 1” to 12” depths
Standard and custom filter sizes available
Designed for high air velocities of 2.0–3.0 m/s (400–600 FPM)
Delivers near-complete contaminant removal efficiency
Extremely low pressure drop, even at higher airflow rates

Tested, Certified & Proven Performance

Tested in accordance with ASHRAE 145.2P and ISO 11155-2
Independently evaluated by leading RTI laboratories in the USA
UL-certified filter media for safety and reliability
Long service life with higher Mean Time Between Replacements (MTBR)
Supported by DRI’s advanced in-house R&D and testing facilities

Key Advantages of DRISORB™ Filters

Ideal solution for space-constrained installations
Higher impregnation loading due to optimised honeycomb geometry
Consistent performance across the entire filter depth
Simple to install, replace, and maintain
Available with multiple impregnation chemistries to target specific contaminants
Suitable for industrial, commercial, and critical infrastructure applications
