I. Product Introduction and Application Scenarios
Pneumatic fire extinguishers and lithium battery-powered blowers are portable equipment used in forest firefighting for suppressing low-to-moderate intensity surface fires, cleaning up residual embers, and creating firebreaks. Pneumatic fire extinguishers are powered by gasoline engines, offering high air volume and high air velocity; lithium battery-powered blowers are driven by lithium batteries, featuring zero emissions, low noise, and easy startup. Both are often used in conjunction with water-based firefighting equipment such as high-pressure relay fire pumps and portable firefighting pumps.
Suitable Working Conditions
- Suppressing low-to-moderate intensity surface fires and grassland fires with flame heights below 1.5 meters;
- Cleaning up residual embers and smoldering fallen logs in burned areas to prevent re-ignition;
- Creating firebreaks by blowing away combustible materials;
- Stockpiled in emergency supply warehouses for routine patrols and initial fire response;
- Used in coordination with water-based equipment such as the LSA-G280 High-Pressure Relay Fire Pump (Stage 2 Pump) — blowers disperse, pumps suppress.
Unsuitable Working Conditions
- High-intensity crown fires and underground fires, which blowers cannot directly extinguish;
- Steep slopes, cliffs, and other terrain where personnel cannot stand safely — blower operation poses high risks;
- Windy weather with winds exceeding Beaufort scale 6 — blower effectiveness drops sharply and units are prone to losing control;
- Lithium battery-powered blowers experience significantly reduced battery life at low temperatures (below -20°C), requiring spare batteries;
- Gasoline blowers require carburetor adjustment at altitudes above 3,000 meters, otherwise power decreases.
II. Core Technical Parameters and Configuration Standards
Key indicators for selection include air volume, air velocity, battery life, weight, and noise. The following are general industry ranges.
| Parameter | Gasoline Pneumatic Fire Extinguisher | Lithium Battery Blower |
| Air Volume | 0.3~0.5 m³/s | 0.2~0.4 m³/s |
| Air Velocity | 80~120 m/s | 60~100 m/s |
| Battery Life / Fuel Consumption | 0.8~1.5 L/h | 20~60 min per battery |
| Unit Weight | 8~12 kg | 3~6 kg |
| Noise | 95~105 dB | 75~85 dB |
| Startup Method | Pull-start | Push-button start |
Configuration recommendation: Each 10-person firefighting team should be equipped with 2~3 gasoline blowers + 2 lithium battery blowers, with lithium battery blowers serving as a supplement for rapid response and residual ember cleanup. Emergency supply warehouses should maintain stock at no less than 1.5 times the number of active personnel.
III. Common Procurement Challenges
When procuring pneumatic fire extinguishers and lithium battery blowers, local users often face the following common challenges:
- Geographic and climatic differences: Local altitude, temperature, and humidity affect blower power and lithium battery life, requiring targeted selection;
- Complex terrain: Mountainous steep slopes are weight-sensitive — lithium battery blowers are more portable, but gasoline blowers deliver greater air volume;
- Limited equipment budget: Gasoline blowers have lower unit prices but higher fuel and maintenance costs; lithium battery blowers require higher initial investment but lower operating costs;
- Qualification and acceptance: Procurement requires test reports, certificates of conformity, 3C certification, etc. Some units require equipment to meet forest firefighting standards;
- Emergency coordination: Blowers need to work in coordination with pumps, fire extinguishers, and other equipment — interfaces and operating logic should be unified;
- After-sales support: Whether local repair service points exist and whether spare parts supply is timely directly affects equipment readiness rates.
IV. Common Misconceptions in Selection and Procurement
- ❌ Focusing only on price while ignoring air volume and air velocity. ✅ Prioritize comparing rated air volume and air velocity to ensure they meet local fire danger rating requirements.
- ❌ Mixing lithium battery blower batteries without matching voltage. ✅ Use original manufacturer batteries, with no fewer than 2 spare batteries per unit.
- ❌ Using gasoline blowers at high altitudes without adjusting the carburetor. ✅ For every 1,000-meter increase in altitude, the carburetor must be re-adjusted or the main jet replaced.
- ❌ Ignoring noise protection. ✅ Operators must wear ear protection; gasoline blower noise can reach 105 dB.
- ❌ Storing blowers long-term without maintenance. ✅ Gasoline blowers require draining fuel and cleaning filters; lithium battery blowers should be stored at 50% charge.
- ❌ Not requiring test reports during procurement. ✅ Third-party test reports and certificates of conformity must be obtained to ensure acceptance passes.
- ❌ Equipping only blowers without pumps. ✅ Blowers are suitable for surface fires; crown fires and residual embers require coordination with water-based equipment such as high-pressure relay fire pumps.
V. Criteria for Screening Reliable Manufacturers/Service Providers
When screening suppliers, it is recommended to evaluate neutrally from the following dimensions:
- Qualifications: Possess firefighting equipment production or sales qualifications; products tested by the National Firefighting Equipment Quality Supervision and Inspection Center;
- Craftsmanship: Mature manufacturing processes for core components such as blower impellers, engines, and battery management systems;
- Testing: Provide test reports for each batch, with verifiable and authentic parameters;
- After-sales: Local or nearby repair service points, with spare parts supply cycles not exceeding 7 days;
- Inventory: Common models in stock, enabling rapid delivery for emergency procurement;
- Lead time: Clear delivery timelines for custom or bulk orders, typically 15~30 days;
- Compliance: Products meet forest firefighting equipment procurement standards and can support bidding and acceptance processes.
VI. Real Project Case Study
An emergency supply warehouse procured a batch of pneumatic fire extinguishers and lithium battery blowers in 2025 for forest fire prevention in its jurisdiction. The configuration was: 20 gasoline pneumatic fire extinguishers (air volume 0.4 m³/s, air velocity 100 m/s) and 15 lithium battery blowers (battery life 40 min per battery, with dual batteries). Additionally, 5 LSA-G280 high-pressure relay fire pumps were procured as supporting equipment. Results: Initial fire response time was reduced to 8 minutes, residual ember cleanup efficiency increased by 30%, and equipment readiness rate remained above 95%. The unit reported that lithium battery blower battery life decreased by approximately 20% in low-temperature environments, which was resolved by adding spare batteries.
Summary
The selection of pneumatic fire extinguishers and lithium battery blowers requires comprehensive consideration of air volume, air velocity, battery life, weight, and local working conditions. During use, attention should be paid to altitude adjustment, battery maintenance, and noise protection. Emergency supply stockpiling is recommended at 1.5 times the team size, paired with water-based equipment such as high-pressure relay fire pumps.
