DCS Panel Cooling Solution – Honeywell 51303940-250 / 51303940-150 | Cabinet Fan Series
Where This Product Is Used
The Honeywell 51303940-250 and 51303940-150 Cabinet Fans are purpose-engineered for thermal management inside distributed control system (DCS) enclosures and industrial automation cabinets. Typical deployment environments include:
- Oil & Gas Refineries – Cooling TDC 3000 / Experion PKS controller cabinets in high-ambient-temperature process areas
- Chemical & Petrochemical Plants – Maintaining safe operating temperatures for I/O modules and power supplies in sealed enclosures
- Power Generation Facilities – Turbine control panel ventilation where continuous uptime is mandatory
- Pulp & Paper Mills – Preventing heat-related faults in multi-card DCS racks operating 24/7
- Water Treatment Plants – Enclosure cooling in humid, corrosive environments
- Pharmaceutical Manufacturing – GMP-compliant control room cabinet ventilation
Wherever Honeywell DCS hardware is installed, these cabinet fans are the OEM-specified solution for enclosure airflow management.

Application-Specific FAQ
Q: What is the difference between 51303940-250 and 51303940-150?
A: These two part numbers represent different fan variants (typically voltage rating or airflow capacity) within the same Honeywell cabinet fan family. Both are used in TDC 3000 / Experion PKS enclosures. Contact us to confirm which variant your cabinet requires based on your cabinet drawing or existing fan label.
Q: Can this fan be used in non-Honeywell cabinets?
A: While physically possible if dimensions match, these fans are optimized for Honeywell DCS enclosures. For third-party cabinets, verify mounting dimensions and electrical specifications before ordering.
Q: Is this a direct replacement for a failed fan?
A: Yes. These are drop-in replacements. Match the part number on your existing fan label to confirm compatibility.
Q: Do you provide a warranty?
A: New units carry the standard Honeywell warranty. Surplus and refurbished units carry a 90-day Konmask operational warranty. Details provided at time of purchase.
Q: Can you supply multiple units for a planned maintenance shutdown?
A: Yes. We regularly fulfill multi-unit orders for planned turnarounds. Request a quote for volume pricing.
