SHANGU® Roots Blower for Live‑Fish Transportation & Holding‑Pond Aquaculture Aeration | MingTian Machinery Complete Solution

Product Overview

Live‑fish tank‑truck long‑distance transportation and factory‑style temporary holding ponds face prominent risks of insufficient dissolved oxygen and rapid ammonia‑nitrogen accumulation. Poor aeration easily causes fish stress response and massive mortality, resulting in heavy economic losses. Stable aeration with clean oil‑free compressed air is the core guarantee for live‑fish survival. As positive‑displacement air‑source equipment, tri‑lobe Roots blowers deliver steady oil‑free airflow. Matched with nano‑microporous aeration tubes or aeration discs, they raise dissolved‑oxygen level in water bodies, restrain accumulation of ammonia‑nitrogen and nitrite, and reduce mortality during live‑fish transit and temporary rearing. They are widely adopted in aquatic‑product circulation plants, fishery terminals and live‑fish transfer workshops. Made‑in‑China adopting US‑Japan reference‑grade technology.

Manufacturing standards, salt‑fog & moisture resistance, blower performance matching and continuous‑running reliability directly determine aeration effect for live‑fish tank trucks and holding ponds. Shandong Mingtian Machinery Group under brand SHANGU is a national‑level Specialized, Refined, Differential & Innovative “Little‑Giant” enterprise. Supported by full‑series tri‑lobe Roots blower portfolio complying with Chinese mechanical industry standards, we serve domestic fishery projects and overseas aquaculture‑equipment exporters. We provide integrated solutions including blower selection, full‑accessory packages and special working‑condition calculation for live‑fish long‑haul transportation and high‑density holding‑pond projects.

Applicable Product Standards

  • JB/T 8941.1‑2014: General‑purpose Roots blowers — Part 1: Technical specifications (Current valid). Specifies overall material requirements, vibration limits and intake‑medium requirements: maximum intake temperature ≤45 °C; solid‑particle content of intake air ≤100 mg/m³. Live‑fish aeration sites are mostly coastal fishery workshops with high humidity and salt‑fog vapour. Intake‑filtration protection shall be adopted to mitigate salt‑fog erosion on impellers and bearings.
  • JB/T 8941.2‑2014: General‑purpose Roots blowers — Part 2: Performance test methods (Current valid). Defines factory‑test benchmark for airflow, pressure and shaft‑power verification. All catalogue performance data of MingTian are obtained under standard intake conditions: 20 °C, absolute pressure 101.325 kPa, relative humidity 65 %. Marked Qs in datasheets refers to inlet flow under this reference condition.
  • GB/T 2888‑2008: Methods of noise measurement for fans and Roots blowers. Official noise‑measurement standard. Holding‑pond workshops and fishery terminals are often adjacent to residential zones; noise output shall meet this standard to avoid public complaints.
  • GB 28381‑2012: Limited values of energy efficiency and energy‑efficiency grades for blowers. Mandatory energy‑efficiency regulation. Holding‑pond aeration usually requires 24‑hour non‑stop running; energy‑efficiency directly determines long‑term operational electricity cost.

Important note on international‑standard equivalence

The test procedure of JB/T 8941.2‑2014 refers to ISO 1217 positive‑displacement compressors acceptance‑test standard, but is NOT fully equivalent. Domestic Chinese test reports cannot directly replace ISO 1217‑compliant reports for overseas projects. For exported aquaculture projects, performance recalculation shall be conducted according to local altitude and coastal salt‑fog ambient conditions. Do not directly apply catalogue Qs parameters.

Critical Unit Conversion (For domestic fishery & overseas export projects, built‑in our product catalogue)

Definition: Qs = catalogue‑listed inlet flow (m³/min) under standard intake state. Overseas aquaculture buyers commonly use CFM for flow; pressure units include kPa, kgf/cm², PSI and mmHg.

  • Flow conversion: 1 m³/min = 35.314 CFM
  • Pressure conversion: 9.8 kPa = 0.1 kgf/cm² = 73.5 mmHg = 1.422 PSI
  • Flow conversion from reference‑state (0 °C) to standard‑intake‑state (20 °C): Qs = Qn × 1.0732

✨ Practical industry pitfalls (rarely published online)

  1. Tank‑truck selection misunderstanding: Many purchasers select blower capacity merely based on tank volume while ignoring pipeline elbows and fouling resistance of microporous aeration tubes. 10‑15 % safety margin for airflow & pressure must be reserved. When aeration holes get clogged in service, insufficient pressure will lead to sharp dissolved‑oxygen drop and heavy live‑fish mortality.
  2. Coastal salt‑fog hazard: Fishery terminals and coastal transfer sites contain salt‑laden vapour. Salt‑fog sucked into blower chamber accelerates impeller rusting and bearing wear. Apart from nameplate parameters, enhanced intake filtration and optional anti‑corrosion coating are strongly recommended.
  3. Shock risk for mobile tank‑truck system: Bumpy driving causes pipeline pressure fluctuation. Hard start‑stop is forbidden. Check valves, blow‑off / relief valves are mandatory. Most blower failures for live‑fish trucks result from water backflow at shutdown instead of main‑unit quality defects.
  4. More airflow does not equal better aeration: Excessive airflow triggers fierce water turbulence, causes fish‑body abrasion and stress injury and increases mortality. Variable‑frequency drive is preferred to adjust aeration volume dynamically according to fish‑loading density.
  5. Airflow attenuation at high altitude: For high‑altitude live‑fish transfer stations, lower atmospheric pressure reduces actual blower output. Working‑condition recalculation is required; plain‑land catalogue parameters cannot be directly adopted, otherwise dissolved‑oxygen shortage occurs.

Working‑condition Challenges & Customer Key Concerns for Live‑Fish Transportation & Holding Ponds

Typical scenarios include aeration for live‑fish tank trucks, fishery‑terminal temporary holding ponds, factory‑style recirculating aquaculture workshops, high‑density fish‑shrimp‑crab rearing tanks. Beyond purchase price, buyers attach high importance to the practical requirements listed below:

  • Stable & oil‑free air supply: Deliver oil‑free clean air to prevent water contamination; capable of 24‑hour continuous‑duty operation. High‑precision dynamic balancing for impellers, unit vibration complies with JB/T 8941.1‑2014 limits.
  • Salt‑fog & high‑humidity resistance: Cope with high‑humidity salt‑laden air at coastal sites; reliable intake‑filtration solution; custom anti‑corrosion coating option available.

Model‑selection tips

  1. For live‑fish tank‑trucks and small‑size holding ponds (tens to hundreds cubic‑metre water volume): Prioritize compact MTS series. It is well‑suited for vehicle‑mount installation.
  2. For factory‑style holding‑pond workshops and medium‑sized fishery‑terminal ponds: Adopt RSR series. Equip check valves and blow‑off valves; VFD configuration is recommended if budget permits.
  3. For large clustered holding‑ponds, long‑distance piping and coastal salt‑fog sites: Choose MTRF / MTRG heavy‑duty models. Calculate full‑set pipeline plus aerator resistance and reserve sufficient airflow‑pressure margin, upgrade anti‑corrosion treatment.
  4. For coastal salt‑fog sites: Upgrade anti‑corrosion coating and high‑capacity intake filter; install full‑set inlet‑outlet silencer packages if adjacent to residential zones.
  5. For fluctuating fish‑stocking density: Deploy VFD control cabinet to adjust aeration output dynamically and minimise fish stress injury.
