Professional Grade IP68, IP67, IP56, IP55, IP54, IP53, and IP51: Durable, Reliable, and Weatherproof

Delta Ingress Protection (IP) rated fans are purpose-built with superior production techniques to prevent dust and water ingress in harsh conditions. IP fans undergo the most rigorous testing against harsh environments, including:

• Rain and flooding
• Salt, fog, and moisture
• Severe dust and dirt exposure

Delta Environmental Proof Fans: In an outdoor environment, a spray of water, exposure to dust particles, unexpected corrosion, and high humidity will all cause the electrical device to work improperly. Delta’s environment-proof fans are designed to use a potting method to seal the PWB to isolate the outside environment. Bypassing the most common standards validation (IP and Bellcore), Delta’s environment-proof fan can withstand outdoor environments or similar conditions.

The IP Code classifies and rates the degrees of protection against the intrusion of solid objects, such as hands and fingers, as well as dust, accidental contact, and moisture or water.

The enclosures are critical to the lifespan and efficient operation of any fan and are built to withstand specific intrusions. To ensure greater durability, Delta provides IP55 and higher protection ratings as an industry standard.

• The second numeral is the rating for protection against water jets.

HIGHLY DURABLE NEW FAN SERIES DESIGNED FOR INDUSTRY 4.0, AIOT, ENERGY, AND HARSH ENVIRONMENTS

Building a next-generation platform? New industrial fans from Delta are the heart of cutting-edge systems focused on Industry 4.0 and AIoT. With the digitization of manufacturing coming to the fore and cyber-physical systems being deployed, a new paradigm of computer-controlled manufacturing is beginning to develop where human intervention may not be required. This level of autonomy requires all components to be reliable and efficient. To achieve performance commensurate with these new industry standards, new Delta industrial fans took design inspiration from the natural form and function of the intricate wings of birds of prey and combined it with cutting-edge engineering simulations across a wide variety of environments and use cases. The result is a new standard impeller and frame design that maximizes performance and operational reliability while reducing inefficiencies.

Industry 4.0 Explanation

• 1.0 – Mechanization, Water power, and Steam power
• 2.0 – Mass production, Assembly line, and Electricity
• 3.0 – Computer and automation
• 4.0 – Cyber-physical systems

Application Examples:

• Solar Inverter Systems
• EV Charger (Homes/Stations)
• Battery Storage/Backup Systems
• Motor Driver and more

Benefits of Delta New Industrial Fans:

• Wide variety of standard products and IP ratings up to IP68 with IP5X stress tested using talcum powder particles
• Nature-inspired impeller design to increase air flow rate and improve blade efficiency

Energy-Efficient Solutions for HVAC, Commercial Refrigeration Fans, and Motors

UP TO 70% POWER SAVINGS WITH ELECTRONICALLY COMMUTATED MOTORS

With global energy savings mandates growing more stringent by the year, AC-based fan motors struggle to keep pace while keeping newer HVAC and Commercial Refrigerator systems working efficiently. To assist our customers, Delta has developed a brushless DC motor technology that is Electronically Commutated (EC) and features an integrated AC-to-DC inverter and magnet rotor. This results in significant power savings over AC motor fans while still maintaining compatibility with current AC source inputs. Our customers can look forward to achieving up to 70% power savings by utilizing Delta EC motor-based fans. This gives our customers the opportunity to offer their end-users an HVAC or Commercial Refrigerator product that offers significant power savings without sacrificing performance.
