Current family context, not an exact specification

Patterson’s current high-velocity fan page lists its 18-inch family at 3,800 CFM and 1/2 HP. That page is a present size-family reference. It does not identify this legacy ASIN, crosswalk its A/B or CS suffix, or establish its motor, propeller measurement, CFM, horsepower, RPM, weight, guard, warranty, voltage, or supplied mount. Those current values are deliberately not stored in this product record as exact-ASIN specifications.

Exact configuration still matters

The exact listing title describes an H18B-CS chain-suspended configuration with 230/460V three-phase wording. The manufacturer page offers multiple mounting options and makes clear that cord information applies only to 115V configurations. Obtain the model nameplate, order quote, and current exact specification sheet before deciding whether the available power, controls, mount hardware, and support structure fit the location. A model code or a similarly sized current fan is not enough.

Use-family comparison carefully

The current family table may help identify documents to request from the supplier, but it is not a substitute for an exact listing record. High-velocity circulation moves room air; it does not by itself establish outdoor-air replacement or a defined exhaust path. Keep this ASIN out of CFM sizing, energy, noise, coverage, and installation comparisons until Patterson confirms its exact motor and mount configuration.

Before you buy

Installation and buying checks

Use these questions to verify the exact configuration. Linked facts are cited; unlisted details stay questions.

  1. Mounting and support

    What mounting method and hardware does the exact unit require?

  2. Clearance and handling

    Do the listed physical details leave enough clearance for installation, adjustment, and service?

  3. Electrical match

    What voltage and connection requirements does the exact unit specify?

  4. Airflow at the job

    Is the listed airflow rated at an operating point that matches the job after placement, obstructions, and system resistance are considered?

  5. Location requirements

    Does the site require an environmental rating or guard? Neither is listed here.

Put 3,800 CFM in context

The Patterson H18B-CS Chain-Suspended High-Velocity Fan has a listed airflow of 3,800 cubic feet per minute. The table compares this rated volume with example room volumes. It does not measure fresh-air exchange, air speed at your body, or room coverage.

RoomSizeNominal room volumes / hourNominal pass interval
One-car garage22 × 12 × 9 ft · 2,376 ft³96×38 s
Two-car garage22 × 20 × 9 ft · 3,960 ft³58×1 min

A circulation fan does not by itself replace indoor air. Exhaust airflow depends on a makeup-air path and system resistance. Use installed outdoor airflow for ventilation calculations.

Formula: airflow × 60 ÷ room volume. CDC explains the ventilation form of this equation; here the input is a catalog rating, so the result is a volume comparison.
