Water Repellent Pre Filter Red

The Water Repellent Pre Filter Red from Outerwears is a purpose-built air intake pre-filter designed to extend engine air filter service life in demanding tactical, law enforcement, and field environments. This round pre-filter wrap fits 10.5-inch diameter filters and protects critical engine breathing systems from dust, debris, and moisture ingestion during high-intensity operations. Field-proven in both military and civilian tactical applications, this product is essential for operators who depend on reliable equipment in unpredictable conditions.

Constructed from durable polyester with advanced water-repellent treatment, the Water Repellent Pre Filter Red sheds moisture and prevents hydro-locking while maintaining optimal airflow to the primary engine filter. The 10.5-inch tall design wraps securely around compatible round filters, creating a sacrificial first-stage barrier that captures larger particulates before they reach the main filter element. The polyester material resists tearing under field handling and dries quickly after exposure to rain, mud, or water crossings—critical factors in tactical and off-road operations where equipment downtime means mission compromise.

Ideal for operators running air-cooled engines in vehicles, generators, compressors, or small-displacement tactical equipment, this pre-filter is particularly valuable in desert, dusty, or wet environments where standard filters clog rapidly. Weighing only 0.08 pounds and measuring 4.85 x 1.55 x 7.3 inches, it installs without modification to existing filter housings and requires no special tools. This is a cost-effective maintenance item that measurably extends primary filter life, reduces unscheduled maintenance intervals, and ensures consistent engine performance during critical operations.
