Diversitech DIVET-400 Fin Comb Tool Set Nylon

Product Description

The DIVERSITECH DIVET-400 is a nylon fin comb tool set designed for straightening bent or damaged fins on HVAC condenser and evaporator coils. Bent fins restrict airflow across the coil, reducing heat transfer efficiency and overall system performance. This set gives HVAC technicians the right comb profiles to restore fin alignment without scratching or gouging the delicate aluminum fin stock. Nylon construction keeps the tool lightweight and resistant to corrosion, making it suitable for regular field use. The set covers multiple fin densities, allowing a single technician to address a range of coil configurations encountered in residential and light commercial work.

This fin tool set is used during routine HVAC maintenance, pre-season tune-ups, and service calls where coil fin damage is identified. It is appropriate for use on air conditioning condensers, evaporator coil sections, and heat pump outdoor units. HVAC service technicians and refrigeration mechanics typically keep a fin comb set in their service van as a standard maintenance tool. The nylon material is safe for use on aluminum fin stock, which is the most common fin material found in residential and light commercial split systems and packaged units.

Key Features

• Tool set format covers multiple fin densities in a single kit
• Lightweight design suited for regular field and service van use
• Restores fin alignment to improve coil airflow and heat transfer efficiency
• Appropriate for condenser coils, evaporator coils, and heat pump outdoor units

Compatibility

Designed as an OEM-style replacement and general-use fin straightening tool for residential and light commercial HVAC coil applications.

Installation Notes

Fin comb work is typically performed by a licensed HVAC technician during maintenance or repair service. Before straightening fins on an outdoor condenser or heat pump, disconnect power at the disconnect box and confirm the unit is de-energized. Work the comb gently through the fin rows in a straight, consistent direction to avoid tearing or further folding the fin material. Do not apply excessive lateral force, as aluminum fins can tear if the comb is misaligned with the fin pitch.
