The provided document is an operations manual for the "BLOWHARD HIGH FLOW JET SERIES PPV Fan." This device is a highly portable, fully integrated AC/DC electric high-speed positive pressure ventilation (PPV) fan, also suitable for general ventilation and industrial applications.
Function Description:
The BlowHard High Flow Jet Series PPV Fan is designed to provide maximum ventilation performance, delivering high CFM (Cubic Feet per Minute) airflow and pressure. Its primary function is positive pressure ventilation, which is crucial for firefighters to clear smoke and hazardous gases from structures. The fan can operate on both battery power (DC) and standard AC power, offering flexibility in deployment. It features a variable speed control, allowing users to adjust the airflow from light ventilation for rehab situations to maximum speed for PPV operations. The fan is engineered to be rugged and durable, ensuring years of service.
Important Technical Specifications:
- Power Source: Fully integrated AC/DC Electric. Operates on standard 110-240VAC outlets.
- Battery Technology: Li-Ion batteries with exceptional energy density and high power in small cells.
- Battery Life Expectancy: Up to 500 full discharge cycles.
- Run Time Performance (Battery):
- Quickee High Flow Jet fans: 40-45 minutes on high speed (PPV), 4 hours on low speed.
- Commando High Flow Jet fans: 45-50 minutes on high speed (PPV), 8 hours on low speed.
- Unlimited Run Time: When operating on 110-240VAC Auto-Switching Power Supply.
- Charge Time:
- 0%-90% capacity (fast charge): 1-2 hours.
- 90%-100% capacity (slow charge): 1 hour longer than fast charge.
- Expected Maximum Power Consumption:
- Quickee: 7A on 110VAC; 4A on 220VAC.
- Commando: 13A on 110VAC; 8A on 220VAC.
- Ingress Rating: IP-67 (No ingress of dust, complete protection against contact. Water projected in powerful jets against the enclosure from any direction or submersion of the base for 30 minutes shall have no harmful effects).
- Motor: Neodymium Magnet Brushless DC (BLDC) motor.
- Propeller Design: Unique blade engineered to increase thrust, reduce turbulence, and deliver exceptionally high-pressure airflow while reducing noise.
- Airflow Capacity: High CFM, with examples like 11,400 CFM and 16,300 CFM mentioned.
- Weight (Total system, including integrated battery and charging circuit):
- Quickee: 46 lbs / 21 kg.
- Commando: 62 lbs / 28 kg.
- Operating Temperature Range for Charging: Optimum 50F-85F (10C-30C). Charging is limited or prevented in extreme temperatures (below 0°C or above 55°C, or below 5°C or above 45°C for slow charge/hot/cold delay).
Usage Features:
- Portability: Lightweight and compact design. Ergo-Fold design allows two fans to occupy the same space as one traditional fan. Ultra-portable for easy storage and transport.
- Variable Speed Control: A power knob allows for variable speed adjustment, from low speed for light ventilation (e.g., rehab situations) to maximum speed for PPV operations. The Electronic Speed Controller (ESC) ensures a smooth ramp-up to maximum speed without power surges.
- Automatic Power Switching: The Battery Management System (BMS) automatically switches to AC power when available to conserve battery power and switches back to battery power if AC is interrupted (provided sufficient battery power is available).
- LED Status Guide: A control panel with LED lights provides real-time status information, including battery charge level, operational status, and error indicators (e.g., bad battery, hot/cold delay).
- "Dead-band" Feature: A "dead-band" between the initial knob click and slow speed operation allows users to check LED power status without turning on the fan.
- Accessories: The fan grill's metallic hub allows for attachments like the Misting Ring and Insta-Click Ducting.
- Emission-free: No gasoline required, making it emission-free.
- No Power Surge: Works with AC outlets from buildings or generators on trucks without causing power surges.
Maintenance Features:
- Integrated Charging System: The battery has an integrated charging system within the BMS, eliminating the need for an external charger. It automatically charges and manages the battery when the fan is plugged in and the power switch is in the OFF position.
- Automatic Battery Maintenance: The BMS performs automatic battery maintenance, including cell balancing for optimized performance, once charging is complete and while the fan remains plugged in. This process can take several hours and can restart during extended periods of non-use.
- Charge After Every Use: Users are advised to plug in the unit after each use, regardless of existing battery capacity, as there is no charge memory (unlike NiCad batteries).
- Battery Protection: The BMS protects batteries from overcharging and over-discharging.
- Periodic Discharge/Recharge: For general maintenance, it is recommended to discharge and recharge the battery every 1 to 2 months to optimize cell performance and allow a system check.
- Battery Replacement: Batteries should only be replaced with BlowHard battery packs. Users are advised to contact the factory with their fan serial number for assistance.
- Disposal and Recycling: Lithium-Ion batteries are subject to specific disposal and recycling regulations. Users should check local regulations and contact battery recycling organizations (e.g., call2recycle.org for USA and Canada). Discharged batteries should be placed in a collection container, with connection points covered to prevent short circuits.
- Self-monitoring Battery: The integrated battery automatically performs maintenance when charging is complete, if needed, provided the fan is plugged in.
The manual emphasizes the importance of reading and understanding the entire operating manual before use to prevent property damage or personal injury. It also highlights the availability of technical support, service arrangements, and warranty services from BlowHard.
