TEMPEST

TEMPEST is a manufacturer of ventilation and smoke ejection equipment used in firefighting, industrial, and emergency response applications. The brand's product line centers on positive-pressure and negative-pressure ventilation fans, smoke ejectors, and the accessories required to deploy them effectively. TEMPEST equipment is commonly specified where high-volume air movement is needed to clear smoke, heat, fumes, or particulate matter from confined or semi-confined spaces. The product families include electric and gas-powered smoke ejectors, ventilation blowers, flexible and smooth-bore ducting, misting kits for evaporative cooling, and fire pumps. These products are used by fire services, industrial maintenance teams, and facility operators who need to manage air quality and temperature during incidents or routine operations. Technical buyers select TEMPEST components based on airflow capacity, duct diameter compatibility, and power source. Ducting is available in inside diameters from 16 inches to 24 inches, with overall lengths ranging from 1 foot to 500 feet, allowing configuration for short-run exhaust or long-distance ventilation. Misting kits are designed to fit fan diameters of 18, 20, 24, 30, and 36 inches, with an 18-inch base diameter and aluminum construction. Smoke ejector models such as 20LU85, 20LU88, 20LU89, and 20LU90 are referenced across multiple duct hose part numbers, indicating a modular approach where the same ejector platform accepts different ducting lengths and diameters. 3G Electric supplies the TEMPEST line as part of its industrial equipment catalog, sourcing OEM parts and accessories for customers worldwide. The catalog includes misting kits, flexible hoses, smooth-bore ducting, and related components identified by manufacturer part numbers such as 725-200, 725-063, 725-071, 725-004, 725-070, 725-021, 725-029, and 725-097. 3G Electric supports procurement by providing part-number-level identification, compatibility data, and logistics coordination for international shipments. For plant engineers and maintenance managers, this means the ability to specify replacement ducting or add misting capability without changing the existing fan or ejector platform. The TEMPEST range is built around standard interface dimensions, so accessories like duct hoses and misting kits are matched to specific fan or ejector models. This reduces the risk of mismatch when ordering spares or expanding a ventilation setup. 3G Electric maintains catalog data that links each TEMPEST accessory to its compatible manufacturer model numbers, helping buyers confirm fit before purchase. The product set is oriented toward operational readiness: ducting that stores compactly, misting kits that mount directly to fan guards, and ejectors that can be powered by electric or gas sources depending on site conditions. For industrial ventilation, firefighting, and emergency cooling, TEMPEST provides a focused range of air-movement hardware and the accessories needed to keep it working.

Frequently asked questions

Common questions about TEMPEST from 3G Electric.

What TEMPEST smoke ejector models are compatible with the flexible duct hoses?

Several TEMPEST flexible duct hoses are listed as compatible with smoke ejector models 20LU85, 20LU88, 20LU89, and 20LU90. For example, the 16-inch inside diameter, 15-foot flexible hose (MPN 725-029) and the 24-inch inside diameter, 15-foot flexible hose (MPN 725-071) both reference these models. The 18-inch inside diameter, 15-foot hose (MPN 725-021) is also used with TEMPEST smoke ejectors. When ordering, confirm the ejector model and the required duct diameter and length. 3G Electric provides compatibility data at the part-number level to help match hoses to the correct ejector.

What fan diameters does the TEMPEST misting kit fit?

The TEMPEST misting kit (MPN 725-200) is designed to fit fan diameters of 18, 20, 24, 30, and 36 inches. It has an 18-inch base diameter and is constructed from aluminum with a silver finish. The kit is used for evaporative cooling in industrial and outdoor settings. Because it mounts to the fan guard or housing, the base diameter must match the fan's mounting interface. Confirm the fan diameter and mounting configuration before ordering. 3G Electric supplies this kit as a catalog item with the manufacturer part number for verification.

What is the difference between TEMPEST smooth bore ducting and flexible hose?

TEMPEST smooth bore ducting is typically supplied in longer overall lengths, such as 500 feet, and is intended for permanent or semi-permanent duct runs where reduced friction loss is beneficial. Flexible hose is supplied in shorter lengths, commonly 15 feet, and is used where the duct must bend around obstacles or be stored compactly. Both are available in inside diameters including 16, 18, and 24 inches. The choice depends on the installation layout, required airflow, and whether the duct needs to be repositioned frequently. 3G Electric catalogs both types with their respective part numbers and compatibility data.

Can TEMPEST duct hoses be used for both firefighting and industrial ventilation?

Yes. TEMPEST duct hoses are used with smoke ejectors in firefighting and industrial ventilation applications. They channel smoke, heat, and fumes away from work areas or confined spaces. The same hose part numbers are referenced for fire service and industrial use, provided the inside diameter and length match the ejector and the installation requirements. For industrial settings, confirm that the hose material and construction are suitable for the expected temperature and chemical exposure. 3G Electric supplies these hoses as OEM parts with manufacturer part numbers for traceability.

What should I check before ordering a TEMPEST duct hose for my smoke ejector?

Confirm three things: the smoke ejector model number, the required inside diameter, and the overall length. TEMPEST hoses are listed with compatibility for models such as 20LU85, 20LU88, 20LU89, and 20LU90, and with inside diameters from 16 to 24 inches. Lengths range from 1 foot to 500 feet depending on the part. Also verify the manufacturer part number against the current ejector setup. 3G Electric provides part-number-level data and can source specific OEM hoses for international delivery.

Does 3G Electric supply TEMPEST fire pumps and ventilation blowers?

3G Electric supplies the TEMPEST line, which includes smoke ejectors, ventilation blowers, fire pumps, ducting, and misting kits. The catalog focuses on the accessories and replacement parts shown in the current product list, such as duct hoses and misting kits. For fire pumps and blowers, availability depends on the specific model and configuration. Buyers should provide the manufacturer part number or model number so 3G Electric can confirm sourcing. The company supports global logistics for these items.
