Bando 4-3V670 Banded V-belt 3V Section 4-rib Neoprene

Product Description

The BANDO 4-3V670 is a narrow banded V-belt engineered for multi-groove drive applications in HVAC, refrigeration, and industrial equipment. Built from neoprene rubber, it resists heat, oil, and ozone degradation that shortens belt life in mechanical room environments. The 3V section profile fits standard narrow-groove sheaves, and the four-rib banded construction ties the belt set together to prevent rollover and reduce vibration during high-load operation. HVAC technicians and mechanical contractors install this style of belt on blower assemblies, condenser fan drives, and compressor drive trains where reliable power transmission is critical.

This belt is suited for residential and light commercial HVAC systems, refrigeration equipment, and general industrial drive applications that call for a narrow 3V section banded belt. The four-rib configuration is commonly found on multi-groove sheave setups in air handling units, rooftop units, and package equipment where a matched belt set is required to balance load across the drive. Install it wherever a 4-3V670 banded set is specified by the equipment manufacturer.

Key Features

• Neoprene rubber construction resists heat, oil, and ozone for extended service life
• Narrow 3V section profile fits standard narrow-groove sheaves
• Four-rib banded design prevents belt rollover and reduces vibration under load
• Drop-in replacement for OEM banded 3V670 four-rib drive belt applications
• Sold individually as a single banded belt set (one unit per package)

Compatibility

Designed as an OEM-style replacement for equipment specifying a narrow banded 3V section four-rib V-belt with a 3V670 base belt designation.

Installation Notes

Banded V-belts are installed by licensed HVAC technicians and mechanical contractors. Before replacing a drive belt, shut off and lock out the unit at the disconnect to prevent accidental startup. Loosen the motor mount or belt tensioner to allow belt removal and installation without prying over sheave flanges, which can damage the rib bond. After installation, verify tension and sheave alignment per the equipment manufacturer specifications before restoring power.
