About this file
This document is a Salient Characteristics specification for a heavy-duty, mobile trommel screen system. The U.S. Air Force (513th ERHS, Tinian MP) is procuring a high-capacity material processing system capable of screening native timbers, roots, soil, and coral into distinct usable material fractions. The equipment must meet minimum technical thresholds including throughput capacity of 180+ cubic yards per hour, a 134 HP Tier 4 Final compliant engine, a screening drum minimum of 6.0 feet diameter by 20 feet length, a hopper capacity of 9.1 cubic yards, an integrated 3-way split conveyor system for simultaneous material sorting, and a wheeled/towable chassis with hydraulic jacklegs for rapid deployment and mobility across rugged terrain. These specifications are established to ensure open competition among qualified manufacturers while meeting rigorous operational requirements.
Delivery is requested by October 1, 2026, to the 513th ERHS located at Tinian MP, 96952. The primary point of contact is TSgt Peter Bessette (Peter.Bessette@us.af.mil), with SMSgt Steven Irons (steven.irons@us.af.mil) serving as the alternate point of contact. The document provides mission justifications for each salient characteristic, emphasizing that the specifications are designed to prevent operational bottlenecks, optimize screening surface area, accommodate large front-end loader equipment, and ensure rapid deployment across variable terrain conditions.

Date: 11 August 2026
1. Overview
This document outlines the Salient Characteristics for a heavy-duty, mobile trommel screen. These specifications are established to meet rigorous material processing requirements while ensuring open competition among qualified manufacturers. The primary mission requirement is a high-capacity, mobile screening system capable of processing native timbers, roots, soil, and coral into distinct, usable material fractions.
2. Salient Characteristics
Requirement Category
Technical Specification Threshold
Mission Justification
Throughput Capacity
Minimum 180+ cubic yards per hour
Ensures high-volume processing to meet project timelines and prevent operational bottlenecks.
Power & Compliance
Minimum 134 HP engine, Tier 4 Final (T4F) compliant
Provides sufficient torque for heavy-duty material separation while meeting strict environmental standards.
Screening Drum Dimensions
Minimum 6.0-foot diameter x 20-foot length
Maximizes screening surface area to optimize separation quality and throughput of mixed raw materials.
Hopper Capacity Minimum 9.1 cubic yards High-capacity hopper minimizes feeding cycle times and accommodates large front-end loaders.
Product Sorting Integrated 3-way split conveyor system
Enables the simultaneous separation and stockpiling of three distinct material sizes in a single pass.
Mobility & Setup Wheeled/towable chassis with hydraulic jacklegs
Ensures rapid deployment, leveling, and relocation across variable, rugged terrain.
