Based on your keywords, you are looking for an industrial centrifugal fan specifically designed for dust collection applications. Here is a breakdown of what your description implies, the specific type of fan you need, and how to ensure you get exactly that.

What your keywords mean:

1. AC Motor: Standard industrial power supply (not DC or variable speed without a VFD).
2. Single Inlet: Air enters from one side of the fan wheel. This is standard for most dust collectors (as opposed to double inlet).
3. Dust Collector Fan: Designed to handle dirty air, typically with a backward-inclined or radial blade wheel.
4. Anti Abrasive: The fan is built to withstand wear from particles hitting the impeller and housing.
5. Long Lifetime: Built with heavy-duty materials (thicker steel) and robust bearings.

The Best Fan Type for Your Needs: Radial Blade (also called "Radial Wheel" or "Paddle Wheel")

For anti-abrasive and long lifetime in a dust collector, you do not want a standard "forward-curved" (squirrel cage) fan. Forward-curved fans are for clean air.

You want a Radial Blade Fan. Here is why:

• Anti-Abrasive Design: The blades are straight, flat, and strong (often made of AR (Abrasion Resistant) steel). They do not have deep cups or curves where dust can pack and cause imbalance. They can handle heavy, sharp, or sticky particles.
• Self-Cleaning: The straight blades shed material easily.
• Long Lifetime: They are built with heavy-gauge steel and robust pillow block bearings (lubricated for long life).
• High Static Pressure: They generate the high pressure needed to pull air through filter bags or cartridges.

Critical Specifications for "Anti Abrasive Long Lifetime"

When purchasing, look for these specific features to match your keywords:

Wheel Material:

• AR Plate (Abrasion Resistant Steel): The best option. Look for materials like Hardox or NM400. This steel is extremely hard and resists wear.
• Thick Gauge: Minimum 3/16" or 1/4" thick wheel plate.

Housing / Casing:

• Thick Liner: Best practice is a standard housing with a replaceable wear liner made of AR steel inside the scroll. This allows you to replace the liner when it wears out, instead of the entire fan.
• Welded Construction (not riveted): For durability in vibration.

Shaft & Bearings:

• Shaft: Large diameter shaft (to reduce deflection).
• Bearings: Pillow block bearings with a removable adapter. Look for self-aligning, spherical roller bearings. These are designed for heavy, dusty environments.

Wheel Design:

• Open Back Plate: To prevent dust buildup on the back side of the wheel (a common cause of balance issues).
• Backward-Inclined Radial (like "RTH" or "RTS" style): Or Straight Radial blades.

Example: Typical Model You Are Looking For

You are describing a fan that would be labeled as:

"Single Inlet, Heavy Duty, Radial Blade Fan for Dust Collection"

A common manufacturer model number that fits this is a Cincinnati Fan RTH Series or a New York Blower RPM Series. These are specifically designed for "abrasive and material handling" and come with AR liners as an option.

Where to Buy & What to Ask For

Don't buy a "general purpose" blower. Buy from a dedicated fan manufacturer.

• Search term: "Radial blade dust collector fan" "AR liner" "single inlet"
• Ask the supplier:
  1. "Is the wheel made of AR400 or higher abrasion-resistant steel?"
  2. "Does it come with a replaceable wear liner in the housing?"
  3. "Are the bearings pillow block with a lubrication line for remote greasing?"
  4. "What is the wheel diameter and motor HP? (e.g., 20" wheel, 10 HP motor)"

Summary (TL;DR)

Verdict: You do not want a "squirrel cage" blower. You want a Heavy Duty Radial Blade Fan with an Abrasion Resistant (AR) Liner.
