Tempest Single-Speed PPV fans are perfect for departments looking to go electric on a limited budget.
AIRFLEX COMPOSITION IMPELLER
Uniquely designed impellers deliver maximum air volume (CFM), velocity and pressure from each Tempest Power Blower™. Every size and type of fan features a blade designed specifically for it to deliver the greatest performance possible. Composite blades are much safer than traditional metal blades as they are designed to disintegrate upon impact of any foreign objects. Metal blades may fragment when integrity is compromised, potentially causing severe injury.
WELDED STEEL ROLL CAGE FRAME
Every bend and cross brace weld is structurally engineered to increase the blower frame’s strength to weight ratio by as much as 30%. Welds eliminate the need to continuously maintain/tighten nuts and bolts. Its roll cage design gives protection to all angles and sides of the shroud and motor.
ERGONOMIC DESIGN
Exclusive frame design makes it convenient to lift, carry and transport. Numerous points on the frame double as lifting/carrying handles. The design itself is the result of three decades of testing, research and experience to create the most ergonomic platform possible.
FOOT OPERATED TILT ADJUSTMENT
No levers to set or knobs to tighten when setting the angle for PPV/PPA. Foot operated adjustment is quick, easy and secure. Allows for up to 5 (4 on 16” models) tilt positions: -5°, 0°, +5°, +10°, +15°.
GFCI COMPATIBLE SINGLE SPEED ELECTRIC
The Single Speed’s 1.5 and 1.0 HP motors are extremely simple to operate with only a single switch used to turn the unit ON or OFF. All models are GFCI compatible and will run on any 15 amp circuit without tripping the breaker. Every Single Speed positive pressure ventilation fan provides impressive CFM capable of creating positive pressure ventilation.
EXPLOSION PROOF OPTION
One of the benefits of a single speed electric motor is its ability to be readily built into an explosion proof housing. The Single Speed EP motor option is rated to operate safely in Class I, Groups C & D and Class II, Groups F & G environments. When dealing with potentially flammable environment, EP is a must. Optional explosion proof ON/OFF switch also available.
16″ Single Speed Explosion Proof Part No. 910-1201
18″ Single Speed Explosion Proof Part No. 910-1221
21″ Single Speed Explosion Proof Part No. 910-1241
24″ Single Speed Explosion Proof Part No. 910-1261
NOTE: Explosion Proof models have the same dimensions as the standard models but weigh more. The 16″ Explosion Proof model (SS-16-S-1.0-EP) has a 1.0 HP motor rated at 7,502 CFM, versus 1.5 HP and 11,804 CFM for the standard 16″ model; the 18″, 21″ and 24″ Explosion Proof models keep the CFM of the standard models.
8″ NON-PNEUMATIC WHEELS
Extra wide 8″ off-road non-pneumatic tires are more durable and allow easy movement up and down stairs, over curbs and large diameter hoses, as well as through rough or muddy terrain. No brakes to forget to lock down or unlock. The PPV fan rests on firm, anti-vibration rubber feet for stability. “Walking” or movement of the fan while in operation is eliminated. Risk of getting clothing in the positive pressure fan’s blades while kneeling to set brake levers is eliminated. 16″ models are only available with 6″ non-pneumatic tires.
TURBO 2000 SHROUD
By redesigning the inward curve and front of the shroud, the Turbo 2000 increases air velocity by up to 30%. The air hitting the ventilation opening is stronger and maintains PPV pressure farther downwind.
FLIP-UP/FOLD-DOWN HANDLE
The exclusive full width handle design makes pushing or pulling the positive pressure ventilation fan to and from the ventilation site quick and easy. The handle quickly swings up to a comfortable height and automatically locks firmly into position. Unlatch and easily fold the handle down for storage at the PPV fan’s listed dimensions.
DUAL “WINNING STEP”
No levers to set or knobs to tighten when setting the angle for PPV. Foot operated adjustment is quick, easy and secure. Dual step allows for adjustment with either foot. Four back and one forward tilt position.
SAFETY GRILLE
Front and rear safety grilles feature a continuous spun wire body with eight tie point bars that also support the “Turbo 2000” shroud integrity. Meets strict European CE Safety Standards.
INFORMATION / SAFETY BAR
Features a large section of durable, reflective material to dramatically increase visibility of the blower from front view and a full list of instructions on the back to allow for safe and effective use.

What is a Tempest single speed electric power blower used for?
A Tempest Power Blower is a positive pressure ventilation (PPV) fan. Tempest’s operations manual says fire departments use it for PPV/PPA to remove heat, gases and smoke from a burning structure, and industrial users use it to control dust, fumes and gases like carbon monoxide in confined spaces.
How PPV works, per the manual: the blower sits outside, aimed so its air pattern seals the entrance opening, or at least 2/3 of it. Pressure then rises equally inside, and once an exhaust opening is made, the interior air moves toward it in one mass.
Which Tempest blower size moves the most air: 16, 18, 21 or 24 inch?
In Tempest’s 2026 catalog the 24″ model has the highest single speed rating, 12,867 CFM. The 16″ SS-16-S-1.5 is the only 1.5 HP model in the 110V/60Hz line: rated 11,804 CFM, it outflows the 18″ (8,748 CFM), slightly exceeds the 21″ (11,698 CFM) and is the lightest of the four.

Explosion proof vs standard Tempest fans: which do you need?
Tempest rates the Explosion Proof (EP) models for Class I (Group C & D) and Class II (Group F & G) environments, and the ON/OFF toggle can also be explosion proof. Match those classes and groups to your site’s hazardous area classification before you choose.
What changes, per the catalog: each EP model keeps its standard model’s dimensions but weighs more. At 16″ the EP version drops to a 1.0 HP motor rated 7,502 CFM; at 18″, 21″ and 24″ the airflow is unchanged.
Where can I buy a Tempest single speed electric power blower?
Choose the size and option on this page (16″, 18″, 21″ or 24″, Single Speed or Explosion Proof), or use the Request a Quote button and give the Tempest part number from the table. The catalog’s single speed table is 110V/60Hz, and Tempest states every model is GFCI compatible and runs on any 15 amp circuit through a single ON/OFF toggle.
