Product Description
The Blower Wheel (also known as the fan impeller) for the Eddy Mark IV heat gun series is a precision-engineered replacement component designed to restore optimal airflow and performance in these iconic USA-made industrial tools. Crafted by Eddy Products in the United States, this blower wheel is an essential part of the brushed AC motor assembly, ensuring the consistent 27 CFM (cubic feet per minute) airflow at 3,300 FPM (feet per minute) velocity that powers the entire series—from the low-temp EP-3ULM to the high-heat EP1100 Plus. Built to withstand the rigors of professional and heavy-duty use, it features a durable, lightweight construction that resists warping, cracking, or imbalance even after years of intermittent or continuous operation. Ideal for technicians, mechanics, and industrial users seeking to extend the life of their Eddy heat gun without full replacement, this blower wheel is a testament to Eddy's 50+ years of commitment to rugged, serviceable design.
Features and Construction
- Durable High Grade Aluminum: Constructed from a durable high-grade Aluminum that outperforms other plastic impellers in heat guns. It resists thermal deformation, vibration from high-RPM operation, and debris accumulation, ensuring balanced spin and noise-free performance.
- Precision Balancing: Factory-balanced to minimize motor wear and extend brush life, reducing the risk of premature armature failure. This contributes to the Mark IV series' renowned longevity, where motors often last 5-10 years under daily use.
- Seamless Integration: Direct-fit replacement that mounts effortlessly onto the armature (rotor) shaft without tools beyond basic disassembly. No need for adhesives or custom modifications—simply remove the old wheel, clean the shaft, and secure the new one for immediate restoration of airflow.
- Maintenance-Friendly Design: Engineered for quick access during routine servicing, aligning with Eddy's philosophy of user-repairable tools. Pair it with replacement brushes or armature kits for a full motor refresh, minimizing downtime in fast-paced environments.
- USA-Made Quality: Proudly manufactured in the USA using domestic materials, this blower wheel upholds the Mark IV's reputation for superior craftsmanship, free from the inconsistencies often found in overseas imports.
This component is more than a part—it's a vital upgrade that breathes new life into your Eddy heat gun, maintaining the precise heat distribution essential for professional results.
Applications
The blower wheel is crucial for any task relying on consistent airflow in the Eddy Mark IV series, preventing reduced efficiency from wear or damage. Common scenarios include:
- Restoring Airflow After Heavy Use: Ideal for automotive shops where dust, paint particles, or prolonged runtime (e.g., epoxy curing or vinyl shrinking) clogs or imbalances the original wheel, ensuring 27 CFM output for even heat application.
- Preventive Maintenance: Recommended during annual servicing for aerospace technicians pre-heating composites or electronics pros de-soldering components, avoiding airflow drop-off that could lead to uneven temperatures.
- Repair After Impact or Debris: For construction and metalworking users who drop tools or work in gritty environments, replacing a cracked wheel restores full velocity for tasks like paint stripping or thawing frozen lines.
- Upgrading Older Models: Extends the service life of vintage Mark IV guns (over 50 years old) for graphic arts drying inks or food processing shrink-fitting, keeping legacy tools compliant and efficient.
By maintaining optimal fan performance, this blower wheel supports the full range of Mark IV applications, from delicate 300°F softening to aggressive 1150°F stripping.
Installation and Compatibility Notes
- Easy DIY Install: Disassemble the motor housing (3 screws), use a 1/8" T handle allen wrench to unlock and slide off the old wheel from the armature shaft, and press-fit the new one. Then use that same 1/8" allen wrench and tighten the blower wheel locking nut. It takes 10-15 minutes with basic tools; no special skills required.
- Compatibility Confirmation: Fits all 120/230V Eddy Mark IV models listed.
