Genuine Dwyer Instruments stock at General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping. The Dwyer Model 460 is a fully mechanical, battery-free air velocity meter with two ranges: 260-1,200 FPM and 1,000-4,000 FPM. It provides direct readings for routine HVAC and ventilation airflow checks. Request a quote in under a minute – call +966 569 289 544.
Product Overview
The Dwyer Model 460 provides a straightforward way to check air velocity at ducts, grilles and ventilation openings without relying on batteries or electronic controls. Its fully mechanical design provides a direct visual reading, making it suitable for routine HVAC and ventilation service work.
The meter provides two overlapping measurement ranges:
- 260-1,200 FPM (approximately 1.3-6.1 m/s)
- 1,000-4,000 FPM (approximately 5.1-20.3 m/s)
Together, the two ranges cover air velocities from 260 to 4,000 FPM. The lower range is suited to lower-velocity airflow checks, while the higher range provides coverage for stronger airflow conditions.
Because the Model 460 is fully mechanical, it requires no batteries or external power. There are no electronic menus or settings to configure. Technicians can select the appropriate range, position the instrument in the airflow according to the manufacturer's instructions and read the velocity directly from the mechanical indicator.
This makes the Model 460 useful for routine checks of supply, return and exhaust airflow. It can also serve as a practical backup instrument for HVAC and ventilation technicians who need a simple instrument that does not depend on battery power.
The Model 460 is intended for direct visual measurements rather than electronic data logging. For HVAC maintenance teams across Saudi Arabia, it provides a simple method for checking airflow at multiple points during inspection and service work.
For very low air velocities, the Dwyer Model 480 is designed for a lower range of 25-400 FPM, making it the relevant alternative for applications such as laminar flow hoods and clean rooms.

Frequently Asked Questions
What ranges does the Dwyer Model 460 cover?
The Model 460 has two ranges: 260-1,200 FPM and 1,000-4,000 FPM. Together, they provide coverage from 260 to 4,000 FPM.
Does the Dwyer 460 need batteries?
No. The Model 460 is fully mechanical and requires no batteries or external power.
What is the Dwyer Model 460 used for?
It is intended for routine HVAC and ventilation airflow checks, including measurements at supply, return and exhaust air points.
Can the Dwyer 460 measure both lower and higher airflow velocities?
Yes. Its lower range measures 260-1,200 FPM, while the higher range measures 1,000-4,000 FPM.
Is the Dwyer 460 suitable for very low air velocities?
The Model 460 starts at 260 FPM. For applications requiring measurement from 25-400 FPM, such as laminar flow hoods and clean rooms, the Dwyer Model 480 is the lower-velocity alternative.
Does the Model 460 provide electronic data logging?
No. It is designed for direct visual readings from its mechanical indicator rather than electronic data logging.
