Product Description
289340X TF-700 Air Compressor – Mack Extended Flange Mount Bendix Replacement
The 289340X TF-700 air compressor is a heavy-duty replacement designed for Mack commercial truck air brake systems that utilize the extended flange mounting configuration. This compressor is available from Ace Motor Parts and is built to deliver dependable airflow for demanding heavy-duty truck applications.
Engine-driven air compressors are responsible for generating compressed air used by the vehicle’s braking system and other pneumatic equipment. The TF-700 series is widely recognized for its durability and higher air output capacity, making it a popular choice for trucks that require consistent air supply during extended operation.
This configuration is commonly used on Mack trucks equipped with extended flange engine mounts. In many installations, the compressor also supports systems that require additional air demand such as auxiliary equipment or power steering assist.
Mack Truck Applications
The 289340X compressor is commonly used on Mack heavy-duty trucks that require a high-capacity TF-700 compressor with an extended flange mount configuration. These compressors are designed to maintain air pressure for the vehicle’s braking system while also supporting additional pneumatic components used on vocational and fleet vehicles.
Because Mack engines often use specialized mounting configurations, verifying the mounting style, port orientation, and engine application is recommended before installation.
TF-700 Compressor Design
The Bendix TF-700 compressor platform utilizes a two-cylinder reciprocating piston design that compresses air through a single-stage compression process. This design provides a reliable supply of compressed air for commercial brake systems used in heavy-duty trucks.
With an approximate displacement of 15.5 cubic feet of air per minute at 1250 RPM, the TF-700 provides higher airflow capacity than smaller compressors commonly found in medium-duty vehicles. The compressor uses engine-supplied lubrication and a water-cooled cylinder head to help maintain stable operating temperatures under continuous use.

The Importance of an Air Compressor in Commercial Brake Systems
The air compressor is one of the most essential components in a commercial truck’s braking system. It continuously generates compressed air which is stored in reservoirs and used whenever the driver applies the brakes.
If the compressor begins to lose efficiency due to wear or internal leakage, the system may take longer to build air pressure. Replacing a worn compressor helps restore proper air pressure levels and ensures reliable braking system performance.
